Fly Biology

Drosophila Genetics

The most recent paper (2017-2019) written primarily with supporting student data and analytics. We are currently in the progress of putting together the data for the upcoming paper, which will feature my year's contributions in the class and lab

GFP (green fluorescent protein) shows expression pattern, and is marked green. DAPI is used as a nuclear counterstain (blue).
Immunohistochemistry microscopy for some example fly lines made by students. What you are looking at are a dissected fly larva's brain (left) and eye disc (right), which, post anti-GFP marking, show the exact enhancement patterns of our GFP-marked insertions. What is most impressive to me is how easy it is to see the neuronal pathways in the brain (with long exons) that express this specific enhancer-trap, and how that can also translate developmentally with the specific tissue in the eye disc particularly lit.

I have been singing professionally since middle school. I have had the gift of attending the late American Boychoir School in its last years, and have learned there many lifelong lessons, among them a technically driven mindset inside and outside of choir. Singing is the most joyous part of any day for me, and I have heavily invested myself in choir in High School beacause of that. I am a section leader now, forever pushing myself and nudging the group around me to look towards technicalities. Outside of choir, I run an acapella group and am part of Exeter's most esteemed vocal chamber ensemble - Gli Scalatori. (we are singing Italian madrigals, and will tour Italy alone this Spring!) Outside of any rehearsals, I still find myself craving time to scratch my music itch. Lately, I have been composing songs. Some of these are personal compositions, made to sing SATB with choir buddies, or for fun game-style projects my friends ask me for musical help with. Outside of personal composition, I have been arranging songs for my acapella group and uploading them on Musescore for the public. I have garnered so far a couple hundred downloads and a few "thank you"s from users online. Feeling like I am using my knowledge in music theory to help the general public adds another layer of enjoyment for the work. I like being the most helpful to the world around me, above all else.

Being a leader, friend, and helping hand in the music scene at Exeter is important to me, as, above being a personal joy to help others, I want to in any way possible continue sharing the gift of professional experience that I received from my now bankrupt middle school.

High School - Phillips Exeter Academy
2016 - 2020
Composition - Musescore -> Soundcloud


    : I enjoy working with others on large scale design projects that require computer science solutions that make the lives of other students at my high school easier. I am co-heading the student council tech committee and computer science club with this mentality. Lately, I have been working on porting the Exeter dining hall app to Android and adding a rating system that dining staff can check online, as well as brainstorm and prototype a QR-code based alternative for attendance check during our school's assembly.

    I am learning more and more computer science design techniques as I go, finding a love for dynamic web site design elements (sometimes using 3d elements as well as JS: check out ECCAPP)

    During the summer, I have been working with close friends on a more lofty computer science website project- - Phillips Exeter's own cybersecurity capture the flag (CTF) geared towards having a larger educational focus than other high school CTFs. I am most proud of the landing page website design I made for the site, but I am also enjoying this summer managing the problem creation team as well as making problems myself.

    I have been spending most of my time lately trying to design better systems at school for students to contribute to larger programming design projects - inside computer science club and inside student council. I am utilizing the connections I've made with faculty, IT, other students, and alumni to give every other student the wealth of resources they deserve.



    : Phillips Exeter Academy Capture the Flag - PEA's own cybersecurity capture the flag (CTF) geared towards having a larger educational focus than other high school CTFs. I personally am responsible so far for the landing page, and am currently working on and managing problem creation for the initial events.

    I made the site mostly from scratch, using only a couple premade CSS functional elements for initial layout. I am most proud of the middle solitaire glitch effect, and the 3d rotating logo at the bottom ~ only using a rotating gif and some CSS rotate functions!

HackNEHS: (Hack New England High Schools) 2019

    : HackNEHS was a New England Hackathon built and run by Phillips Exeter and Andover students in 2016 and 2017, which then lost focus once the founders graduated, and did not hold a competition in the past two years. Joining up with a persistent group of Andover and Choate students, I, along with most of the Exeter Computing Club Board, have been working to make this contest a reality again for 2019, running with free admission for the benefit of the students in the general Massachusetts area.

    I have personally been in charge of revamping the site, as well as the outreach to potential sponsors. I am hopeful towards getting the event off the ground for an October launch date!

P Element Insertion Location Tool

    : A tool I helped fellow intern at Dr. Kim's Drosophila Lab , Sanath, develop. It started initially as a python script written by Sanath, used to optimize our own specific workflow. I helped him port it quickly to JS and give it a semblance of a user interface to be hosted on a dummy website. We then started collaborating to generalize the inputs to streamline the script across use cases further than our own lab.

    What the site does is take the "raw" sequence data of the inverse PCR reaction inputted, "cleans" the signal based on any possible digest used, and then BLASTs the "clean" sequence against the fly genome on flybase. Based on the BLAST hit data, the script quickly tells you the likely insertion location, orientation, and what primers could be used to amplify the missing end.

    Although a good exercise the first times, finding multiple insertion locations for multiple lines and designing optimal primers by hand becomes tedium. This simple script has already saved us hours of work, and can hopfully save hours of work for real scientists who actually get paid.

Site Github


    : One of my favorite sites to make - ECCAPP is a dummy site that presents my application materials for the board of Exeter's Computer Science Club, but in a unique way: One half of the site consists of youtube videos floating in a 3d viewfinder, and the other utilizes the special transparency properties of png images to give a double meaning. I spent way more time then I should have on this stupid project, but I hope you enjoy how the end result looks, so if you can ignore the singing and content, I think the website stands well on its own.

NOTE: The website currently does not work due to an update in the three.js library it is built upon. I tried to find a quick fix, but have given up in supporting the project, as the application was over with before the update. You can enter the site to view the working animation and transparent png page, but the camera is not functional. The video on this page shows quickly what the site contained.

Exeter Dining Hall Menu App

    : This past year, as a tech committee head, I have led the continuation of the development of Exeter's Android dining hall app.

    To me, past giving every android user an updated menu based on their dining hall of preference, the most important addition to this project was the ability for the dhall staff to see ratings and comments from students on specific dishes and menus. We have been working hard to make the analytics dream a reality, making a heroku applet that the dining hall staff can access to easily dump the ratings into a spreadsheet in real-time. I cared about this project because I wanted to make it as impactful and helpful for the student and faculty body alike.

Tazawa-Sensei Bot

    : A Discord chatbot that helps the users (my Japanese class, and possibly the general public) in learning Japanese by mediating Kanji recognition and stroke order games, custom or prebuilt vocabulary deck quizzes, or by playing the famous Japanese vocabulary game Shiritori.

    Made using the Discord chatbot framework in Node.js, and run personally on Heroku
