PhD students

Padryk Merkl

PadrykPadryk Merkl is a PhD student in Dr. Georgios Sotiriou’s group in the department of Microbiology, Tumour and Cell biology at Karolinska institutet. He graduated in 2017 with an integrated masters degree in chemical physics from the University of Edinburgh, during this time he spent 13 months as an industrial placement student at Unilever in Colworth studying hair using confocal Raman spectroscopy supervised by Dr. Paul Pudney. He wrote his master’s thesis on an ab-initio computational study of the phase stabilities of neon hydrates conducted under the supervision of Dr. Andreas Hermann. He also spent a summer working in Dr. Colin Campbell’s group at the University of Edinburgh investigating the use of surface enhanced Raman spectroscopy for 3D cell culture analysis. He is now looking forward to applying himself to developing novel nanobiotechnological tools to study and manipulate biological systems.
