Writing the literature review section for a scientific research article can be a daunting task. This blog post is a summary of what I have personally found to best help when writing about scientific research. I hope some of these tips can help make the process an easier and more fulfilling experience!Continue reading Writing a Literature Review? Some Tips Before You Start
Beginning a research project is often a daunting task. Often, when I begin a project, I have the vaguest idea of what to research. Sometimes, I don’t know where to begin looking. Given that Firestone is one of the largest open stack libraries in existence, there are literally millions of books, journals, anthologies, and other pieces of literature to sift through. The process of identifying the literature that will propel a research topic is thus often the most tiring part, but thankfully, there is a solution: the wonderful Princeton librarians!
So, who are these librarians?
In fact, each undergraduate student at Princeton is assigned their own personal librarian. This librarian is supposed to act as your direct liaison between the library system and yourself. You can go to them to receive guidance on how to navigate the stacks, learn how to take advantage of different workshops and programs, or even just have a chat. My personal librarian, Ellen Ambrosone, almost always sends me an email every semester to remind me of her services. Often, she also includes a picture of her dog! Regardless, these librarians are meant to be friendly faces in a huge space, so do reach out to them with any inquiries about your research or the library system writ large!
The Princeton University Library system also hosts a large array of different subject librarians, each specializing in their own discipline. For example, Steven Knowlton is one of the subject librarians for both History and African American Studies. Thus, a student interested in a topic pertaining to History and/or African American Studies might want to reach out to him in order to identify literature that may be pertinent to your research topic.Continue reading Lost in the Library? Turn to a Librarian!
These days, it seems like every day we learn of a new variant of SARS-CoV-2 (the virus that causes COVID-19). However, it’s hard to understand what a variant is and how it changes the virus. In this post, I wanted to introduce PyMOL, a program that students have access to through the University. This program can be used to see what the spike protein and its mutations actually look like.
But first, here’s some background on SARS-CoV-2: COVID-19 is a disease caused by a strain of coronavirus called SARS-CoV-2. This virus gets inside the human cells by using something called a spike protein. This spike protein binds to a receptor on the human cell called the ACE2 receptor, and this allows the virus to infiltrate the cell. The variants of SARS-CoV-2 that we keep hearing about typically have different mutations on the spike protein. In the case of the B.1.1.7 variant, which is a variant that is thought to be 30-50 percent more infectious than other variants in circulation, the mutations are at a location that allow the spike protein to bind better to the ACE2 receptor. If you bind better to the receptor, you’re better at infiltrating the cell. The spike is also the target of the vaccine and our natural immune system.
Now, let’s try and look at where these mutations actually are.Continue reading Visualizing COVID-19 Mutations Using PyMOL, a University Provided Resource
As I just passed the deadline for my junior independent work (JIW), I wanted to explore strategies that could be helpful in composing a research proposal. In the chemistry department, JIW usually involves lab work and collecting raw data. However, this year, because of the pandemic, there is limited benchwork involved and most of the emphasis has shifted to designing a research proposal that would segue into one’s senior thesis. So far, I have only had one prior experience composing a research proposal, and it was from a virtual summer research program in my department. For this program, I was able to write a proposal on modifying a certain chemical inhibitor that could be used in reducing cancer cell proliferation. Using that experience as a guide, I will outline the steps I followed when I wrote my proposal. (Most of these steps are oriented towards research in the natural sciences, but there are many aspects common to research in other fields).Continue reading How to Write a Research Proposal as an Undergrad
For this Spring Seasonal Series, entitled Doing Research in a Pandemic, each correspondent has selected a researcher to interview about the impact of the pandemic on their research. We hope that these interviews document the nuanced ways the pandemic has affected research experiences, and serve as a resource for students and other researchers. Here, Nanako shares her interview.
For this seasonal series, I decided to interview Emily Mesev, a Ph.D. candidate in the Department of Molecular Biology. I was interested in how her experience as a graduate student differed from my experience as an undergrad. Because undergrads aren’t allowed to be in the laboratory (at least for Molecular Biology), I’ve had to change my thesis topic and redirect it to become computational. I was excited to find out whether the graduate student experience had changed in similar ways!Continue reading Doing Research in a Pandemic, An Interview with Molecular Biology Graduate Student Emily Mesev
“What? Why would I ever need to read an article about how to write an email?” This is what my first thought would’ve been if I ever saw an article like this. While many Princeton students probably understand the basics of how to write an email (type, then hit send), today, I wanted to go over tips to use when “cold emailing” someone.
Before coming to Princeton, the emails that I wrote were sent to my friends and high school teachers. I’d only ever emailed people that I already knew. However, throughout the years, I’ve learned that email is wonderful ⎯ and useful for research ⎯ because you can contact people who you don’t already know! Although learning how to write emails is something that’s not taught formally, I think it’s increasingly important to know what to do and what not to do when you’re trying to catch the attention of someone you’ve never met or talked to.Continue reading How to Write An Email To Someone You Don’t Know
Most people’s New Years Resolutions, I imagine, are not about improving their knowledge of statistics. But I would argue that a little bit of knowledge about statistics is both useful and interesting. As it turns out, our brains are constantly doing statistics – in reality, our conscious selves are the only ones out of the loop! Learning and using statistics can help with interpreting data, making formal conclusions about data, and understanding the limitations and qualifications of those conclusions.
In my last post, I explained a project in my PSY/NEU 338 course that lent itself well to statistical analysis. I walked through the process of collecting the data, using a Google Spreadsheet for computing statistics, and making sense of what a ‘p-value’ is. In this post, however, I walk through how I went about visualizing these results. Interpretation of data is often not complete before getting a chance to see it. Plus, images are much more conducive than a wall of text when it comes to sharing results with other people.Continue reading A Quick Crash Course in Statistics: Part 2
In PSY/NEU 338, From Animal Learning to Changing People’s Minds, my group recently presented our capstone project for the course: we researched irrationality, trying to understand when humans make irrational decisions, how that is implemented in the brain, and if certain things might actually be incorrectly labeled as ‘irrational’. Our emotions are a leading example: although some call them irrational, in practice, they play a key role in fine-tuning our decision-making and reasoning abilities. When you’re happy, for example, everything might be going more positively than expected. Your mood is thus encouraging you to continue the behaviors that led to those rewards, since that positive trend might continue (for a neuroscientific discussion of this topic, see this paper).
To demonstrate this phenomenon first-hand, we had students in the class play what is known as the Ultimatum Game:
You are the proposer. You have been given $100. You are tasked with splitting your money with a stranger, the responder. If the responder accepts the split that you propose, you both keep the money after the game ends. If the responder does not accept, no one keeps the money.
The question: how much money do you decide to offer the responder?
After reading this, students had five seconds to provide their answer. They were then asked to report their mood. The question we wanted to answer was simple:
Is the amount of money people offered statistically different between those who reported “positive” versus “negative” moods?
In this post, I’ll explain some of the basic statistics I used to formally answer this question, bolding some key terms in the field along the way. In my next post, I’ll walk through the programming aspect for visualizing those statistics.Continue reading A Quick Crash Course in Statistics: Part 1
It’s said that a picture tells a thousand words; a map, however, can tell you a million.
To me, maps are not just tools for navigation. They have a variety of uses, enabling their creators to visualize a vast array of data efficiently and quickly. From questionable election forecasts to the location of monuments in a city, anything of your choosing can be mappable. Maps, in my experience, can be one of the most powerful tools in your research toolbox. Thus, I want to show you how you can use maps in your research, and the power they hold!Continue reading Lost and Confused? Create a Map!
Presenting on Zoom can be difficult, as you must now learn how to keep a virtual audience engaged. Last spring semester, after returning home due to COVID-19, I had to quickly learn how to make this transition, as I was enrolled in CBE346: Chemical Engineering Laboratory (core lab). This course was laboratory based, and it consisted of 4 different lab rotations, after which all students had to complete a written report and a presentation. Due to the pandemic, 3 of those were completed over Zoom.
In this post, I will give tips on how to prepare for a Zoom presentation, using the insights I gained from my core lab presentations.Continue reading How to Prepare for an In-Class Zoom Presentation
