I worked with Professor Dvira Segal for three summers after my sophomore, junior
and senior year.
My research in Dvira's group focused on charge transport through DNA.
Specifically, I, Hyewang Kim and Michael investigated
conductance and thermopower of GC-rich DNA sequences in the intermediate
coherent-incoherent regime.
We used DFT-NEGF (Landauer), complemented with Buttiker probes to model electron-phonon
scattering during the passage of charge carriers through long chains. This method allows
one
to calculate transport properties (thermal and electrical conductance, thermopower,
figure of merit etc.)
for any system hamiltonian. This talk neatly
summarizes the DNA charge transport project.
In the summer after my freshman year, I worked with Dr. Shaked
Rosenne
under the supervision of Prof. Boris
Rybtchinski
as a participant of the Kupzinet-Getz
summer research program at the
Weitzman Institute of Science, Israel. There I
explored self-assembly of
perylene diimine (PDI) derivatives in aqueous medium. During an 8-week program,
I did a small organic synthesis and analyzed the aggregates using UV-VIS Absorbance,
Fluorescence, SEM and cryo-TEM.

I voluntered in
Fekl
lab as a freshman, exploring metal-organic synthetic approaches,
aiming at novel derivatives of adamantane and learned a lot of important synthetic
skills. Associate Professor Ulrich Fekl at the
University of Toronto
Mississauga campus together with his graduate student
David Armstrong were my first supervisors in university.
I also attended my first chemistry conference, the
Inorganic Discussion Weekend-2014 as a member
of Fekl lab.
In grade 11 (final grade in Ukraine) I worked with
Associate
Professor Oleksandr Yanchuk at the
Eastern-European National university in my
hometown, Lutsk.
There I was developing electrochemical synthesis of ZnO nanoparticles
to achieve uniform shape, and to reduce particle size and polidispersity.
I presented this project at several competitions, and won multiple awards, including
first prizes at all three of
MAS-2014,
Intel-Eco Ukraine
(national stage of
Intel ISEF) and the National Ecology Olympiad.
In grade 10 I studied pigment and heavy metal content in the leaves of
decorative trees as a part of my ecology project with
Dr. Halyna
Yagenska (my biology and ecology teacher) and
Assoc. Prof. Vasyl
Voitiuk from department of Biology at the
Eastern-European National university. I and my
partner, Repetylo Iryna, presented this work at the International Ecology Project
Olympiad, INEPO-2013 in Istanbul, Turkey and recieved highest score among about 100
projects from 45 countries, coming home with a gold medal each.
My first research project was the study of Cerebella of aquatic fish in grade 9 with Prof. Yaroslav
Omelkovec
at the Eastern-European National university in my
hometown, Lutsk.
This project was supported by the Minor Acedemy of
Science (MAN),
an organization that funds research projects of high school students under the
supervision of
professors at the local universities. I presented it at the MAS yearly competition in
grade 9, resulting in my first small victory (third prize) at the research contest.
