Counselors 2020


Daniil Lukin

Graduate student, Stanford University

My PhD work is 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. 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 Lukin

Software Engineer

I have come to Sigma Camp as a student since the very beginning, and have felt how fun and interesting this camp truly is. I love to discuss and hypothesis different crazy ideas, something like constructing a large scale Stirling engine that would run from the equator and down to Antarctica, thus producing the much needed energy for the human race. I would love to listen to other people's amazing ideas, even if they are as unrealistic as mine. Outside of my studies, I love playing music, running, and sometime rock climbing!



Andrey Khesin

Graduate student, MIT

I have been at SigmaCamp since the very beginning. I will be starting my PhD in Math at MIT this year. I am always open to chat about math, physics, or even computer science! At SigmaCamp, you can usually find me at the Sigma Special Event, workshops, or the evening clubs. Alternatively, you might find me at the dance classes or facing off in chess or ping-pong. I try to find time to play guitar, so if you want to jam together, let me know!

My research has been all over the place. I have worked on a project involving partial differential equations, written several papers in knot theory, worked on the geometric transportation problem, and spent a summer working with ATLAS and at CERN. Currently, I am dabbling in entrepreneurship and launching a startup with an incubator program named the Next 36.


Alex Frenkel

Undergraduate, UC Berkeley

This will be my fourth year as a counselor at Sigma Camp. I am graduating from UC Berkeley as a physics major this May (2019), and I will be pursuing a Ph.D. in theoretical physics at Stanford University as an NSF Fellow afterwards. My current research is in the realm of quantum gravity, and for my graduate work I will be studying both high energy and condensed matter theory. My other academic interests include math, computer science, political science, and history.

I play a lot of tennis, some chess, and enjoy following both tennis and other professional sports.



 Natasha Butkevich 

Cornell University Alumna

I am delighted to return to Sigma for my fourth year on the SigmaStaff, and sixth year overall. My academic interests include microbiology and infectious disease (mainly bacteria, although I am fascinated by parasites and other minuscule creatures), marine science, immunology, and printmaking. In my free time, I enjoy making detailed drawings, watercolor paintings, and/or three-dimensional, geometric structures out of paper using unnecessarily complicated printmaking processes. Recently, I’ve picked up ballroom dancing (after 12 years of ballet); I lead Latin/Rhythm and follow Standard. I’m excited to meet everyone online at SigmaCamp this year!


Zofii Kaczmarek

Research Associate, Beyond Meat

Hi! This will be my fifth year as a counselor at Sigma, and it will certainly be a unique one. I'm looking forward to exploring the challenge of running an online camp, as well as the possibilities and creativity that these new constraints inspire.

I'm currently working at Beyond Meat, in their R&D/Innovation department. I didn't expect to work on food company, given that my background is in microbiology and physics, but it's exciting to be working on plant-based meat and at a company that prioritizes sustainability.

Outside of work, I spend my time social dancing and playing games, and I organize a monthly contra dance. Of course, those have been mostly put on hold during the pandemic, but I look forward to the days when our communities can come together in person again.


Lev Bershadsky

Undergraduate, Harvard College 

Lev goes to Harvard College and is a member of Harvard Undergraduate Robotics team. He has attended Sigma camp as a camper 3 times and was counselor last year. Lev was a member of National Honor Society, and he participated in Quiz Bowl, math teams, and Science Olympiad. Other than STEM, Lev enjoys tennis, sailing, and kendo. During his time at Sigma he ran a workshop that taught people how to fly quadcopters and build rocket engines. Lev was teacher's assistant at School Nova where he assisted a 7th grade math class. In his spare time Lev likes to build multirotors and destroy the patriarchy.


Sophia Abanov

Undergraduate, The University of Chicago

I have been coming to Sigma since the very first year, and I’m excited to be back for my fourth year as a counselor. I am a math major at UChicago and I’ve also taken several classes in physics, computer science and economics. In my free time, I like staying active and though I’m not particularly great at any sport, I’ve dabbled in quite a few like soccer, volleyball, gymnastics, and cheerleading. One of my favorite things at Sigma are workshops. I enjoy teaching them and attending those done by other counselors because everyone at Sigma is really really cool and has amazing things to share. One workshop I have taught in the past is about the geometry that can be found within the card game SET.


Jacob Kudria

Undergraduate, Stony Brook University

Hi! I just finished my sophomore year at Stony Brook University: I’m a pre-med student pursuing a major in applied mathematics and statistics, with minors in chemistry and biology. This will be my 8th year with Sigma, and 5th as a counselor. As you can probably tell by the mouthful above, I’m curious about everything and can’t seem to settle on one subject - ultimately I chose to major in math, although I do still want to go into medicine. Outside of academics you can find usually find me reading anything I can get my hands on (fiction and nonfiction), or else finding new music to explore. I’m excited to meet new faces and reconnect with the old, so lets make the most of virtual Sigma!



Priya Srikumar

Undergraduate, Cornell University

This will be my fourth year as a Counselor at Sigma, and I couldn't be more excited to meet all of you! I study computer science, and I'm particularly interested in robotics, programming languages, and algorithm development. I speak Tamil, French, Korean, and a little Russian (though I'm still learning!). I’m an avid reader of both fiction and nonfiction; come talk to me for book recommendations! I also practice several combat sports, including boxing, wrestling, and Muay Thai. I enjoy debating (I am on my school's team), and greatly enjoy stimulating discussion. More than anything, though, I treasure getting to know you as a camper and connecting with you about your own interests and experiences. I can't wait to see you at Sigma!


Nestor Tkachenko

Undergraduate, Harvard College

Hello, I'm Nestor and I'm very excited to return to sigma camp as a counselor again! I love doing new things, exploring possibilities nobody has ventured through and creating what has never been thought of. I hope to share my love of creativity and innovation with all of you and help you discover your passions.

I am personally very interested in physics and technology as well as entrepreneurship. I do everything from building robots and creating levitating vehicles, to shocking people to make them dance. I’m currently working on creating an electric scooter sharing service in Cambridge for college students.

I also 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!
