Counselors 2022

Daniil Lukin

Postdoctoral fellow, Stanford University

My PhD work was related to making nanoscale optical structures and manipulating quantum states of individuals atoms, with the goal of contributing to the world-wide effort on making optical quantum computers -- I'm continuing along the same lines now as postdoc. When I go to Sigma, I like to bring with me various tech contraptions so we can take them apart. This year, we will breaking into a turbo-molecular vacuum pump. I also participate in teaching dance, teach physics-related workshops, and play classical guitar.


Andrey Khesin

Graduate student, MIT

I have been at SigmaCamp since the very beginning. I am working on my PhD in Math at MIT. I am always open to chat about math, physics, or computer science! At SigmaCamp, I usually run the semilab "From A to B", the oobleck workshop, and the Mafia and Hanabi evening clubs. Additionally, I greatly enjoy square dancing and contra. I try to find time to play guitar, so if you want to jam together, let me know! My research is in quantum computing and quantum information theory. I am investigating how efficiently can classical computers simulate quantum computation and how much does having access to entanglement help spatially-separated parties trying to measure simultaneously to determine an unknown quantum state.


Alex Frenkel

PhD Student, Stanford University

Hi Everyone! This will be my (oh god) - eighth?! year at Sigma, having joined for the first time as a counselor right before college. I am now entering the fourth year of my PhD, splitting my time between Stanford in California and Cambridge in England. My main field of study is quantum gravity and string theory, although I'm broadly interested in all of physics and work on some condensed matter theory projects as well. Besides work, I love tennis (having played almost my whole life), basketball, and chess, and am happy to go on about any of them on end. I really look forward to meeting all of you, and learning about your interests!


Luigia Than

Graduate Student, NYU

Hello, I'm super excited to be back for another year as a counselor at Sigma! I'm a grad student at NYU studying electrical engineering. In undergrad, I was part of a team designing wearable medical devices, and I also worked on an art display to highlight collaboration between the art and engineering schools. In my spare time I enjoy making art (digital, traditional, and textile!) and playing board/card/tabletop games. Recently, I've been experimenting with making video games. I'm excited to get to know all of you this summer!!


Alexander Suponya

Undergraduate Student, Rutgers University

Hi everyone! I am a rising junior studying biomedical engineering and CS at Rutgers. After spending a summer and semester doing neuroscience research at Rutgers, I'm hoping to find a way to pursue my interest in stem cell research. I'm also a huge fan of all things linguistics — an often overlooked scientific field. I play the piano and guitar, so any song recommendations during camp are welcome. Cheers to another year of learning from one another and making wonderful Sigma memories!


Alec Douglas

Graduate Student, Harvard

I'm a Harvard Physics Graduate student. My PhD work is related to simulating exotic materials, such as high temperature superconductors by trapping and observing the collective behavior of many atoms tapped by light. In particular we can simulate the behavior of insulating materials by mapping the behavior of electrons hopping around in a crystal of atoms to atoms hopping around in crystals made of light.

When I'm not in the lab I enjoy biking, rock climbing, video and board games.


Anastasia Zhurikhina

Graduate Student, Georgia Tech

I am a PhD student in Biomedical Engineering trying to save the world through synergetic combination of computational and experimental biology by squeezing the most out of my applied mathematics and physics BS degree. My thesis is related to cracking the problem of brain blood vessels abnormalities that lead to hemorrhagic strokes. I have some experience in teaching as I've taught physics and biomechanics for high school and college students. The process of outlining the classes, stumbling upon unexpected questions and pulling consultational all-nighters with cookies for my students feels like part of my habit now. Aside from that I am an art and sport enthusiast: painting, photographing, swimming, windsurfing, kiteboarding, rock climbing, playing tennis, badminton, stretching and etc.


Natasha Butkevich

Graduate Student, Stony Brook University

I am delighted to return to Sigma for my sixth year on the SigmaStaff, and eighth year overall. My academic interest falls at the intersection of marine science and microbiology - I'm working on vesicle production in E. huxleyi and spend time thinking about viral gene transfer in the oceans or the role oceans play in the global carbon cycle. If that sounds interesting, feel free to find me and we'll talk. In my 'copious' free time, I enjoy making detailed drawings or the occasional three-dimensional structure using unnecessarily complicated printmaking processes. I’ve picked up ballroom dancing (after 12 years of ballet), and I'm down to try anything artsy or active. Looking forward to meeting everyone this year!


Zofii Kaczmarek

Research Associate, Beyond Meat

My background is in physics and biophysics, but now I work mostly on chemistry (go figure!) and other analytical testing. At my work, I develop methods to characterize food samples, and I think about how to make data easily and quickly understood. I also look for ways to improve communication and other coordination processes between team members. On the dance floor, I practice improving my own communication and coordination processes with friends and strangers. I enjoy blues, fusion, west coast swing, tango, and contra dancing. I also run a monthly contra dance, and I’m president of a local dance cooperative.

This will be my 6th year with Sigma, and whether I’ve met you before or we’re meeting for the first time, I’m looking forward to seeing you!


Arina Nikitina

Graduate Student, Georgia Institute of Technology

This is going to be my fifth time being a counselor at Sigma. I love this place; although sometimes I can seem moody - don't worry, it’s just my normal face. I am a graduate student at Georgia Tech’s Bioinformatics PhD program. Back in Russia I taught math to students in grades 5 - 11. Aside from my work and studies, I love music; every year at Sigma I try to find like-minded people to perform as a rock-band at the Talent Show!


Sophia Abanov

Trader, Akuna Capital

I am a 2021 graduate of the University of Chicago where I studied math and computer science, and I currently live in Chicago and work as a trader at Akuna Capital. At my job I get to work on interesting projects of my choosing and I constantly apply principles of calculus, statistics, probability, and my (sadly pretty weak) programming skills to my work. Outside of work, I like stay active by doing gymnastics, volleyball, and coaching cheerleading for my former college team. I also love playing soccer and tennis whenever I get the chance. Most of my remaining free time is spent reading and watching shows; my favorite book I’ve read this year is a series called The Three Body Problem and my favorite show is Severance. If anyone has book or show recommendations, I’d love to hear them! This year will be my 7th year as a SigmaCounselor. My favorite part of the camp is interacting with all of the campers and staff, and I also love that Sigma is a learning experience for campers and staff alike. Every year I learn so many new things from lectures, tournaments, workshops, and just from talking to other people. I’m counting down the days until August 14th and can’t wait for another great camp!.


Nikita Podobedov

Undergraduate, Columbia University

I've been coming to Sigma since the beginning, and I'm really excited to be here for another year. I recently finished my undergrad studying biomedical engineering and computer science and I’m going to be starting a PhD at MIT in the fall in biological engineering. Outside of STEM, I'm interested in history, geography, and linguistics. I love trivia, and I used to play quiz bowl at my university. I also really enjoy playing racket sports, and I'm looking forward to organizing the ping pong tournament at Sigma again. Looking forward to seeing everyone this summer!


Nestor Tkachenko

Founder/CEO of Rito

Hello, I'm Nestor and I'm very excited to return to in-person Sigma as a counselor again! My primary work is as a professional Dogecoin investor, but on the side I'm a founder of a food robotics startup called Rito which I dropped out of Harvard to start. I also love philosophy, iced lattes, and hot takes.

I am personally very interested in physics, technology, and entrepreneurship. I do everything from building burrito-making robots and creating levitating vehicles, to shocking people to make them dance.

I love meeting new people and enjoy understanding how others think, and always appreciate interesting discussions on any topic, from questions of morality to cultural trends, so feel free to talk to me about anything!


Melissa Guidry

Graduate Student, Stanford University

My scientific research is on quantum photonics. I engineer optical circuits to study the quantum mechanics of light. One device that I often engineer is a “microring”, a micron-scale ring-shaped optical cavity: once light enters the ring, it can travel around thousands of times before it exits, going around in tight circles with a circumference close to that of a human hair. This intense optical confinement enables interesting physics: for example, we can convert one color of light to many other colors, often entangling the new colors of light in the process. Some researchers are trying to use this phenomenon to build chip-scale quantum computers. Outside of the lab, I like to read. My favorite books I’ve read this year were The Red and the Black and The Portrait of a Lady.


Giuseppina Than

Undergraduate, Stony Brook University

Hello! I was a camper at Sigma for five years and am so excited to come back as a counselor! I am studying Biomedical Engineering at Stony Brook University. Biology is one of my favorite subjects, and I've done research projects on gene expression and variant nucleosomes (ask me about it if you're interested). Beyond STEM, I love Broadway (I've performed and stage managed for my school's theater club!), making music (piano and flute), and reading (Lord of the Rings is the best!), among other things. Come talk to me about anything - I'm always interested in learning something new!

Boris Barron

Graduate Student, Cornell University

Hello everyone! I'm Boris and this will be my first time at Sigma. I tend to have very broad interests (biophysics, mechanical engineering, laser physics, evolution, etc.) which I like to summarize as saying that I am interested in the 'best' way to solve a problem. Most recently, I have been working on using information theory to create demographic models (where the available data is insufficient to capture the full complexity of the system) during my PhD in physics at Cornell. Outside of academics, I have a similarly eclectic background: I have lived in 4 countries (Israel, Canada, England, USA) and competed at a note-worthy level in ballroom dancing while doing running, taekwondo, ballet, swimming, and dragon boat somewhat more moderately. In the last few years I have been nowhere near as active as I should be and spend most of my free time chasing big ideas or not thinking much at all (video games). Happy to talk about anything!
