Kaloian Koynov
Group Leader Kaloian
Koynov studied physics at the Sofia University and received his diploma
in 1993. In 1997 he received his PhD from the same university for a
work on cascaded nonlinear optical processes and their applications for
all-optical switching in the group of Solomon Saltiel. Then he spent a
postdoctoral year in the Institute for Fundamental Electronics,
University Paris Sud, France, studying grating couplers into
semiconductor waveguides. In 2000 he joined the department of Wolfgang
Knoll at the MPI for Polymer Research as a postdoc and EU Marie Curie
Fellow. Here, he worked with Christoph Bubeck on the nonlinear optical
properties of thin films of conjugated polymers. Since 2006 he is a
group leader in the department of Hans-Jürgen Butt at the MPIP, where
he leads the Fluorescence Correlation Spectroscopy group. In addition,
he is in charge of the service laboratory “Mechanic / Dielectric
Properties” that provides numerous possibilities for characterization
of macromolecular materials.

Yaolei Xiang
Postdoc Yaolei
Xiang got his bachelor's degree from Northwestern Polytechnical
University, China in 2014, majoring in Theoretical and Applied
Mechanics, and a doctoral degree from Peking University, China in 2019,
majoring in Solid Mechanics. From 2019 to 2021, he worked as a postdoc
with the support of the Boya postdoctoral fellowship program at Peking
University. In October 2021, he joined Dr. Kaloian Koynov's group as a
postdoc to study charge effects in droplet sliding by using ultra-fast
high resolution microscopy. His research interests are electro-sliding
on solid surfaces, wetting on structured surfaces, and flow control
mediated by the liquid-gas interface.

Karina N. Catalán
PhD Student Karina was born in Santiago, Chile. She
received her Bachelor and Master’s degree in Physics at the Technical
University Federico Santa Maria in Valparaíso, Chile. During her
Master’s thesis she worked on the design and construction of an
electrospinning chamber for the fabrication of polymeric nanofibers
whose swelling properties were further studied with an afm with ambient
control. Since 2021 she’s performing her PhD studies at the MPIP
studying wetting and dewetting properties of polymeric coatings using
fluorescent probes.
Besides work, Karina loves doing sports, traveling and playing musical instruments. Besides to her work, she likes dancing and painting. |

University of Science and Technology of China (USTC). Since 2014, the
third year in undergraduate study, she joined Prof. Tongwen Xu’s
research group, carrying out highly hydroxide conductive ionomers with
fullerene functionalities. She continued her master’s degree in Applied
Chemistry under the supervision of Prof. Tongwen Xu and Prof. Zhengjin
Yang at USTC. For her master thesis, she studied hyper-branched
polystyrene copolymer makes superior anion exchange membrane. Now as a
PhD student, she is working on photoresponsive materials at the MPI for
Polymer Research.

Physics in the Universidad Técnica Federico Santa María, Valparaíso
Chile. During his master thesis, he made his research at the MPIP,
using AFM to study capillary and friction forces in the group of
Michael Kappl. His experience as researcher also includes AFM to study
mechanical properties and cell adhesion measurements. Currently, he is
doing his PhD with the supervision of Kaloian Koynov, using high
precision optic instruments to study wetting interactions and drop
charging.
Outside his work as researcher, Diego enjoy Music and art in general. |
