Virtual Sigma 2020: Counselors

Trader at Akuna Capital
Sophia Abanov

This will be my 8th 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.

In 2021, I graduated from the University Chicago, where I studied math and computer science, and I currently live in Chicago and work as a trader. 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 to do gymnastics and I also volunteer as a cheerleading coach for my former college team. I also enjoy playing soccer, volleyball, and tennis, though I’m not very good at any of them.

Lev Bershadsky

Lev goes to NYU, and he was a member of the Harvard Undergraduate Aeronautics Club. He has attended Sigma camp as a camper 3 times and was a counselor before. Lev was a member of his high school's competitive Roblox team, and he participated in Quiz Bowl, math teams, and Science Olympiad. Other than STEM, Lev enjoys tennis, sailing, and environmental advocacy. During his time at SigmaCamp, he ran a workshop that taught people how to fly quadcopters and build rocket engines. Lev was a teacher's assistant at School Nova assisting a 7th-grade math class. In his spare time, Lev likes to build multirotors and destroy the patriarchy.

Graduate Student at Stony Brook University
Natasha Butkevich

I am delighted to return to Sigma for my seventh year on the SigmaStaff, and ninth year overall. My academic interest falls at the intersection of marine science and microbiology - I split my time between studying marine vesicles and determining the key bacterial taxa and their contributions to chemoautotrophic and heterotrophic processes in the Eastern Tropical North Pacific oxygen minimum zone. Otherwise, I 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 abstract drawings, dancing, or training for the next spartan race. 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!

Graduate Student at Harvard
Alexander (Alec) Douglas

I am a graduate student studying physics at Harvard. I work on cooling atoms to ultracold temperatures (10^-10 Kelvin) in order to observe behavior similar to electrons in insulators. In particular I work with magnetic atoms that quantum tunnel to move around and interact at distances like tiny bar magnets. These atoms can realize exotic states of matter such as crystals that flow without resistance, as well as other collective phenomena.

In my spare time I can usually be found playing with my cats or skiing.

Graduate Student at Boston University
Sofiya Filippova

Hello everyone! I am a masters student at Boston University studying product design and manufacturing in the mechanical engineering department. I am passionate about developing clean technology and building a more sustainable world! After graduation, I hope to work as a design engineer streamlining clean technology commercialization. Outside of academics, I love to rock climb, do yoga, ski, and generally spend time outdoors. I am also a big reader and love making and viewing art. But that’s enough about me, I want to learn about your passions! Find me at camp to talk to about anything and everything. I am so excited to return to Sigma for another summer and help make this an unforgettable week for all the incoming campers, as my counselors once did for me!

PhD Student at Stanford University
Alex Frenkel

I am currently a grad student studying quantum gravity and string theory, primarily based at Stanford University but also spending a lot of time at the University of Cambridge in the UK. My primary research interests are in how the fabric of spacetime emerges from strongly interacting chaotic quantum systems, and in the nature of black hole microstates within these systems. At Sigma this year I will teach two semilabs - one on Cosmology (the study of the history and eventual fate of our universe) and one on black holes and how we think about them from both a classical and a quantum perspective.

I am always very approachable, especially if you want to chat about physics or hear me rant about tennis :-)

Project Manager at Beyond Meat
Zofii Kaczmarek

My background is in physics and biophysics, but now I work as a project manager at Beyond Meat. I work closely with food scientists and research scientists, as well as teams outside of the R&D department, to make sure new projects are on track and meeting key targets. I develop processes to improve communication and make frequent and important tasks easier and more fool-proof. I think of myself as someone on a curling team — smoothing the ice in front of the stone, and calling out when course-corrections are needed. On the dance floor, I also practice improving communication and coordination processes. 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 8th 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!

Graduate Student at Stony Brook University
Jacob Kudria

Hello! I am currently getting a master's degree in Neurobiology and Behavior, working in a lab that studies how neurons talk to each other at a synaptic level in the brain. That said, my passion is for translational medical research, so ultimately, I hope to go to medical school. Outside of academics, I volunteer as an EMT in my community, love to ski, and can most often be found hiding away with a good book. At SigmaCamp, I do a variety of things, from taking photos of everyone to helping with the chamber concert. By far though, my favorite part is meeting all the campers, greeting old and new faces alike. I look forward to seeing you all soon!

Postdoctoral Researcher at Stanford University
Daniil Lukin

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. I don't know yet what we will breaking into this year. Together with Melissa Guidry, I teach the Optics semilab. This year, we will be using light to do measurements and computations, in particular, image processing using Fourier transforms.

Software Engineer
Andrey Lukin

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. I am currently pursuing my Bachelor degree in Computer Science at Georgia Institute of Technology. Outside of my studies, I love playing music, running, and sometime rock climbing!

a girl
Graduate Student, Georgia Tech
Anastasia Zhurikhina

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.
