Rotation Students (2018~)
Pelayo Jose Carlos (Jan-Apr 2020)
I obtained my Master's degree in physics from the University of San Carlos (Philippines) and a diploma in theoretical physics (1 year master program) from International Center for Theoretical Physics (Italy). My previous studies are primarily in the field of theoretical condensed matter physics while my current interests are still in condensed matter physics with the addition of quantum information, and quantum thermodynamics. In my free time I usually play computer games and read manga.
Nico Fischer (Sep-Dec 2021)
I studied physics in Jena, a small university town in eastern Germany, where I worked on different approaches to holography (the one in high energy physics, not optical holography). Part of this investigation was a 5-month internship at OIST in the Quantum Gravity Unit with Prof. Yasha Neiman. Now in my 3rd rotation, I would like to learn more about spin liquids and related novel phases of condensed matter, especially (but not only) to better understand the recently discovered connections between spin liquids and black holes. When not doing physics, I like to invest time learning Japanese, read novels, or try out scuba diving in the beautiful waters surrounding Okinawa.
Yuta Ito (Jan-Apr 2018)
I’ve earned my master degree in astronomy at university of Tokyo. After some thinking, I decided to pursue my doctorate degree here at OIST, a place that gives the chance to reexamine my interests in an amazing environment. Although, I explored the galactic dynamics during my master program, recently, I started being fascinated by condensed matter physics which is also about many-body system, just like galaxies, but consists of quantum particles such as electrons. In addition to studying, I’m interested in various things including sports, music, movie, books, English, trip, etc. If I have the opportunity to try interesting things, I would love to challenge myself.
Tim Keller (May-Aug 2018)
I obtained my Master's degree from Saarland University in Saarbrücken (Germany) in the group of Giovanna Morigi, where I studied the out-of-equilibrium dynamics of small ultracold atomic systems and the fascinating properties of quantum crystals of matter and light, formed by the process of atomic self-organization in optical cavities. At OIST, I hope to learn more about many-body and condensed matter physics, especially about collective quantum effects at low temperatures like novel states of matter. Outside of physics, I enjoy being around and inside Okinawa's beautiful ocean and exploring the island.
Irina Korshok (Jan-May 2021)
During my master’s at Saint Petersburg State University, I studied the effects of superradiance in Rb vapor systems under the femtosecond laser pulses. After that, I applied for an internship at OIST, and, eventually, for a PhD. My interests are lying in the applied physics and math area, where I use various numerical methods and/or machine learning for a wide range of physical problems. This is my third rotation where I am planning to make a project by using Monte-Carlo methods and C++. Besides science, I like walking, trying new food, and drawing.
Keerthy Menon (May-Aug 2020)
I am a forever-24 year old physics enthusiast hailing from Cochin in the south-west coast bordering the beautiful Arabian sea, Kerala. I have a Master's degree in Physics from Central University, Karnataka, India with a specialization in quantum mechanics. I have formerly worked in quantum foundation problems namely wave particle duality in double slit experiments. Recently my research interests have developed into ultra cold quantum gases and theoretical condensed matter physics. Besides Physics , I love music, cooking and sunsets in the beach
Friederike Metz (May-Aug 2018)
After studying in Germany, the US, and Canada, as well as traveling around the world, my journey brought me all the way to Okinawa, where I am now a first year PhD student. Academically, I am similarly curious and have worked in the fields of astrophysics, quantum information, and particle physics. In my free time I enjoy snorkeling, discovering this beautiful island, and learning Japanese.
Sarika Nair (Sep-Dec 2020)
I did my master’s degree from university of Kerala. After that I joined as a research assistant in IISER Mohali, India. I am interested in quantum physics and I enjoy to explore the strange phenomenon’s in nature using the novel ideas of quantum physics. I have research experience in quantum optics. In future I want to extend my research experiences into BE condensate, Quantum matter, Quantum foundation, Quantum information, Quantum cryptography etc. Along with observing nature I love travelling, reading and spending time with friends.
Weber Natalya (Jan-Apr 2020)
I'm a WIS graduate with a degree in chemistry. I came to OIST, because it allows me to keep sciencing away while exploring new avenues of interest. In my spare time I hang out with a blind cat, trade pennies with random people, try to ask the right questions and strive to be aware in every possible way.
Darya Stepanenko (Jan-Apr 2018)
Motivation for me is to make the world, we live in, a better place. One can do this either by being a doctor, a teacher or, may be, a scientist.
I was too bad in biology to become a good doctor, therefore I decided to become a physicist. Thus, I found myself in Moscow Institute of Physics and Technology. After graduating with Bachelor degree in Applied Physics and Math, I came to OIST to finally make an impact in medicine as a physicist.
Mountains attract me a lot, I like hiking and trekking. But I came here to Okinawa, where there are almost no possibilities to go closer to the sky. On the contrary, the minus level above the sea is reachable easily. Sea is more like mother for soul, while mountains is father. Originally, I am from Kazakhstan, mountain country, I spent a lot of time living nearby father, it's time to live nearby mother.
Simone Tandurella (Jan-Apr 2022)
My journey to Okinawa begins in my hometown of Naples, Italy where I studied for my BSc in Chemical Engineering at UniNa. From there on I moved to TU Delft (Netherlands) in order to pursue an MSc in that same field. My graduation project has focused on a machine learning approach to the modelling of biomass pyrolysis yields, and has left me a taste for modelling and computational statistics. I began my studies at OIST in September 2021, but my journey to the island has yet to end as I am currently still remote. As part of my out-of-field rotation I joined TQM unit, where I plan to learn new perspectives that may come in handy for my future endeavours. Apart from research, I love, in order: cooking, eating, photographing, walking, sitting and reading, and plan to do lots of it in Okinawa!
Yuta Yamazaki (Jan-May 2021)
I got my master's degree from Tokyo Tech in Japan. My major is molecular biology, biochemistry, and cell biology. I participated in TQM unit as an out-of-field rotation student. I'm happy to learn machine learning here because I have been shocked by Deep learning technology, especially in Go. I like playing Go so it was really shocking for me to know that AI, called Alphago, that is much stronger than professional Go players were invented using deep learning technology. I want to learn as much as possible here during lab rotation!
