The Amazing Sara - volleyball-playing, fly-crossing, chocolate-eating grad student extraordinaire.

Posted by Hetali Lodaya on 2009-06-25 - one comment

Note to the reader: so my PI, Dr. Steve Haase, sort of doesn’t like interviews… and was conveniently very busy most of this week. He replied to my email with, “You know, you should probably just interview Sara. It would be more interesting anyway.” And so, with a laugh and some trepidation, the wonderful Sara Bristow, a 2nd-year grad student and my mentor in the lab, agreed to talk to me. Me recording the conversation sort of freaked her out. But I think we had fun anyway :) And I’ll delete the recording, as promised. Potentially I can make Steve do an interview next week. Until then...

Where did you do your undergrad?

I did my undergrad at Georgetown in Washington, D.C. It’s a fun place. And I was a biology major. It was kind of strange being a biology major, but not being premed, because everyone biology is a premed at Georgetown. Actually I think that’s pretty common everywhere, I know here at Duke it is. And so not knowing really what I wanted to do, knowing I definitely didn’t want to go into medical school put me in kind of a weird position, because everyone else was like, “I’m going to medical school, and that’s why I’m taking all of these classes!”, and I was just taking them because I liked biology.

Have you always liked biology?

Yeah. Yeah since I was, oh man… I think the first class I ever had biology in was in 5th grade, and a student teacher came in, and I just fell in love. She ended up working at the school, and taught my 7th and 8th grade science class. So that was really cool, and since then I’ve sort of taken every biology I could – or science I could, and so I hit college and started on biology.

What made you decide biology in particular, compared to other sciences?

Well, compared to chemistry and physics, I felt like I understood it better, and it was sort of easier for me to relate it to the world around me, you know. I could look at water and be like “oh, the molecular formula is two hydrogens and one oxygen”, but when you think about water and how important it is to life, and think about how we use it in our daily lives, that’s pretty cool. That’s what got me interested.

What was your favorite class in when you were an undergrad?

I would have to say intro biology, because it the first day of class, my professor stood up on the desk, in front of the whole class of 200 of us, and pretended to be an antibody. That was really cool, and he was just really captivating, and kept my interest in biology. It was a really hard course, he made the tests really hard, mainly to weed people out. And so I think if I hadn’t enjoyed that course, I probably would have changed majors to something else. Not quite sure what. But I probably would have changed majors.

Do you have any idea at all what you would have done? Like, if you weren’t in grad school right now, what would you be doing?

Probably teaching… maybe high school. I toyed with the idea of taking two years off and doing Teach for America. Actually as a college student, as a senior, it was mandatory that we had to do a thesis, and there were three options. You could do a research from looking at journal articles and coming up with a theoretical experiment, you could do research in a lab, or you could do a teaching thesis, and I went into a high school in D.C. and taught biotechnology. And so, that kind of got me a little interested in teaching, and I seriously thought about doing TFA for a while. But, I ended up wanting to go to graduate school, because then I can do research and I can teach at the same time. I can TA, and I get to mentor, like you and Chenchen, and it’s really cool. I hope I don’t mess you up too much, because this is my first time doing it. But it’s been pretty cool so far to see how those two things come together.

*Insert long discussion about how I want to teach and do research too! And how I’ve always thought Teach for America is awesome. And how it’s cool that you can do both teaching and other careers with each other. *

It’s pretty cool how it comes together, because in graduate school, not only are you required to TA, but even if you’re not assigned to mentor, you’re always working together as a group. You know, if someone has a problem, it’s not just you figuring it out on your own. It’s very collaborative. It should be a very collaborative work experience. I mean, like Yuan-Jie will come up and say, “How do you do this?”, and I’m like, “Well, I do it this way, but Laura does it this way, and Mark does it a different way,” and so there’s not one right way. Which is what’s pretty cool about science. Because with math, or physics – there’s certain equations that you have to follow, certain procedures. With biology, it’s, “How will I do it? Will it get me the right answer? I sure hope so…”

What do you like to do in your free time?

Well, I like to play volleyball, so I’m on a volleyball team – summer league, we play on the sand. I like just relaxing… during the summer I like to go to the pool, the beach, I like running and reading, I’m trying to start knitting. That’s been a challenge – knitting is a challenge. You have to have a lot of patience and discipline. Yeah, I just like hanging out… mainly volleyball. Played in high school, I tried to start a team in college, but my friends don’t really like volleyball. I didn’t want to put in the time commitment of a travel team because every weekend, you’re gone. The nice thing about being a graduate student - I guess it depends on the lab you’re in - with Steve, you can pick your hours. If you need a mental health day you can take it.You can work on weekends if you want, you can work four really long days and have a three day weekend, so that’s the good thing about grad school.

Are there any big stories of catastrophes or experiences or learning that you want to share, from undergraduate, from working here?

Like bad things that have happened in the lab?

Sure. I mean, things that somebody could learn from. Or things that made you stop and think, or realize something about what you were doing. That’s a really loaded question, I’m sorry.

Well, in terms of experiments, so I’m working with fruit flies, and I’ve been trying to do these crosses. I have one gene in one fly and another gene in another fly, and I want to get them both in the same fly, and it takes four separate crosses for that. To keep things very simple, you use - since they’re diploid, you have your mutation on one chromosome, and on the other one you have a balancer, so there can’t be any recombination. And so what I was using as a balancer was a phenotype where the flies have no eyes. And I’m doing a cross, and I’m not getting any of the flies that I think I should be getting, and I’m like, “What is going on here?”, and I realize that the mutation I’m working on is cell cycle related. Well, to have no eyes, you have no division of your eye cells… so, two mutants in the cell cycle together make it so that you can’t get any flies. So, I had been doing the cross the wrong way for like 2 months… so that’s a learning experience. It really teaches you to think about how you set things up, and the details of, “Oh, I’m just going to use this so that everything stays the same.” But you have to make sure that what you have controls for anything.

What else… I broke a lot of glass in my organic chemistry lab. It’s a very hard class, and the labs are four hours long, and you’re under the hood all the time. And the first day – it’s the only day where the lab professor will walk around, and I broke like three things on that day. I left crying, and I was like, “I don’t know if I can do this!” Because I realized that to take a biology class I wanted to take, I had to take organic chemistry, you know? So I left crying and, well, you just realize that it happens to everybody… it just happened to me a lot that day.

*Insert story about how I broke a lot of glass in chemistry workservice. You should ask me. It’s a funny story. Anyway.*

It kind of fueled my fire to try harder, which I think I like that about my personality. I don’t think a lot of people have that. So all of my experiences have taught me determination, I think, which is important in science. As you saw with Chenchen, it can get very, very upsetting if something isn’t working and you can’t figure it out, but it happens to everybody. And when it works, the joy is so great - how great it feels to make something work is really cool.

Last question. I’m trying to pick which one of the fun ones I can use. Okay, if you could be any flavor of ice cream, what would you be?

I would have to be – does it have to reflect my personality? I just really like chocolate. And it would have to be the chocolate ice cream from this ice cream store at my dad’s beach. Because it is perhaps the best chocolate I’ve ever had in my life. So it would have to be chocolate from King’s Ice Cream – *I pointed out that she's wearing a shirt from the ice cream store*  – oh yeah, there you go. Yup, chocolate. Their chocolate is so good, I don’t know what they do to it, but, yeah. That would be it.

Well, thanks for being a sport.

That wasn’t so painful after all!

No! Of course not.
 

Reading journal articles isn't like normal reading? That explains everything.

Posted by Hetali Lodaya on 2009-06-23 - 6 comments

The biggest thing to keep in mind when you're reading a journal article is that it's NOT like reading a book. If you try to just read it straight through, it makes your head hurt, especially if it's not a topic you're very familiar with in the first place. It helps to sort of think like the researcher who did the project, and understand the paper as you would if they just sat down and explained it to you. So, the magical order for reading journal articles, courtesy Mr. Bob Gotwals:

1. Abstract - the little blurb at the beginning that describes the research question, the methods, the results, all in summary. You probably read this first anyway, especially if you found the article on your own, but this section is crucial, often because it will tell you whether the paper's even relevant to what you're doing. If there are any words you don't understand here, look them up right away because you'll see them a lot.

2. Introduction - Usually the next section of the paper, this will outline the background behind the field being investigated, often getting narrower and narrower as you understand why the researchers are even interested in this question. By the end, you should know exactly what the research question was.

3. Conclusion - Sounds like cheating, but the idea here is that you know what the question is - jumping to the conclusion lets you find out what the answer ended up being. Was the hypothesis supported? What additional questions were raised? In the end, what was the point? If you understand what happened, you are better prepared to understand how they figured it out.

4. Results and Discussion - Now get into details. What specific conclusions did they come to? How did they interpret their data? Make sure that you understand the thought process and reasoning behind the interpretation of the data. 

5. Graphs and Charts - You should have been looking at these as they were referenced throughout the article anyway, but now concentrate on all of the figures in the paper. Think about your understanding of the data and results and see how that is being represented visually. Axis labels/titles/captions are crucial - don't just look at the pretty pictures!

6. Materials and Methods - Often, you don't even really need to read this section. It is useful if you are going to be conducting a similar experiment or assay. If so, you can compare what you are doing to the method used, or perhaps modify your protocol if something worked for them that didn't work for you. This section comes last because it's so specific - it either applies to you or it doesn't.

Hope that makes wading through the sea of literature a little easier. Just a couple of general pointers:

  • Your highlighter is your best friend! Use something, anything to mark up your paper/write notes in the margins. If you need to look for a specific piece of information later, you won't have to reread the whole thing.
  • dictionary.com and wikipedia are your next best friends. They are quick and easy resources if you come across a term you don't know, and usually fairly thorough.
  •  It's often helpful to type up a summary of an article after you read it. If you have a lot of papers, you won't necessarily remember what each one is about or why it was useful to you.

Have fun reading! :)

You wish you played with nerf guns in your lab.

Hey scientists, fellow HH students and mentors, and of course, Kriti. My name is Hetali Lodaya and I'm a rising senior at the North Carolina School of Science and Mathematics. I also went to Chapel Hill High School - I've lived in a fair number of different places throughout my life. I love a lot of different things - reading, sci fi/fantasy lit, Indian dance, percussion, Bollywood music, mint ice cream, writing, and, yes, science. This summer, I'm lucky enough to be doing research in the Haase Lab at Duke University as part of the Howard Hughes Precollege Program. My lab is interested in the cell cycle, particularly in the factors that regulate its oscillation.

You'd think that I would be tired of research by now - last summer I did a project looking at the effects of piceatannol on the COX-2 enzyme as a potential avenue for cancer therapy. In my Research in Computational Science class at school, I am currently exploring stilbene molecules and their ability to bind to the p53 protein. Here at Howard Hughes, if my lab's hypothesis is correct, it's going to fundamentally change our understanding of the cell cycle and what drives it. That's TOO exciting.

Part of the grad office. My desk is next to the scooter. Say hi to Danny the dolphin!

And I think ideas like that are making me realize how much I love research. If you had asked me before any of this experience, I would have thought that I would HATE the idea of there not being a right answer. But that is what makes research amazing - you are looking for steps to move closer to the right answer. You have the opportunity to look at a pile of data and really understand what it means, and then write it up and explain it so that other people can use your steps on their own path. I love that feeling, and I'm really excited to see what I can get my yeast to tell me this summer.

My lab is also part of the VIP Program, another Hughes initiative that combines stats/math/computational work with lab data to do "systems biology" research. As a part of understanding the cell cycle's oscillatory process, it is useful to build a network of the transcription factors that we think are involved, a sort of map that models the different interactions key to the cell's periodicity. The three undergrads from this program working to solve this question are Blake, Yiwen, and Chenchen.

Blake and Yiwen are doing the stats/modeling work - I sometimes follow them around and try to understand what they're saying about Eigen vectors and models that blow up to infinity. They use the data that Chenchen is developing, and that I will be contributing to, regarding the budding cycles of different yeast strains with various genes and transcription factors knocked out. All three are very cool - I hang out with them when they are working on their presentations for VIP or going to seminars, and they're all really funny and bright.

The wonderful Chenchen and Laura. And Bud, the yeast, in the corner.

 

Also in the lab we have Sara and Laura, two grad students who basically know everything. I'm really excited for Sara to come back, because she'll be helping me develop my specific project. There's also Mark, a postdoc who knows even more of everything, who keeps really late hours - he comes in the late afternoon and stays until about midnight. Rounding out the bunch we have Yuan-Jie, a postdoc, and Dave, another postdoc who will be leaving soon - he wrote the current model that we use to understand our cell cycle data, CLOCCS. Of course, there's Dr. Haase himself, the wonderful Steve - believe me, when you don't know how to you something, you'll get Steve'd (more about that later). It's a great way to learn new things from someone who first started on this topic ten years ago when he published a paper in Nature. Just another aspect of research - you never know where the questions you start with will take you. We're all excited to see where the work will go from here. For now, I have homework - over the weekend, I'm going to be putting together a flowchart detailing where I want to go with experiments over the entire six weeks of the program, and writing up my protcols for each step of the way. To be submitted Monday for revisions and Steve-ing!

Oh yeah, and Nerf guns. Did I mention those? The picture says it all.
