Contact: dominic.winter[at]

After finishing his PhD in the group of Wolf Lehmann at the German Cancer Research Center in Heidelberg, Dominic joined the lab of Hanno Steen for postdoctoral studies at Children’s Hospital / Harvard Medical School in Boston, USA. After returning to Germany, he started as group leader at the IBMB. Being trained initially in mass spectrometry and proteomics, he extended his range of skills to a variety of biochemistry and molecular biology techniques allowing the Winter Lab to cover almost every aspect of the projects they are working on. If you don't find Dominic in his office, you should have a look in the forest where he likes to climb hills on his bike or at the river Rhine where he is rowing or trying to catch some fish.


Name: Dr. Robert Hardt
Position: Post Doc
Special skill: The data muncher

Robert is a "Bonner Original" and already conducted his diploma and Ph.D. studies in the IBMB, were he developed and applied LC-MS-based proteomic methods to study a myelin membrane protein involved in a severe neurodegenerative disease. After finishing his Ph.D. in 2015, Robert joined the "Core Facility for MS & Proteomics" at the ZMBH in Heidelberg. There he further expanded his practical and theoretical knowledge in mass spectrometry and helped many customers solving their analytical questions. The foci of his work were large scale PTM-analyses, targeted measurements (PRM) and crosslinking-MS. From 2017 to 2019 he then applied his skills in the pharmaceutical industry at Sanofi in Frankfurt a. M.. There he analyzed various recombinant proteins by classical "bottom-up" as well as "top-down" approaches. After two years, Robert decided to move back to academia and is now working as a joined PostDoc both for the mass spectrometry core facility and the Winter lab. Besides mass spectrometry and research, Robert is an enthusiastic rower and runner, as well as a movie and TV series addict.

Name: Shiva Ahmadi
Position: PhD student
Special skill: The singer

Shiva came to Germany in 2011 to obtain her Master’s degree in Molecular Biotechnology. Initially she joined the Winter Lab for a practical course; apparently, she liked it a lot here and stayed for both her Master’s and Ph.D. thesis. In the lab, she does various techniques ranging from cloning over the generation of viruses and their transduction to proteomics. Using SDS gels and western blots, mass spectrometry and cell culture it is all around one major topic: Gaucher disease. All that work doesn't mean she has no time for herself. She is a passionate traveler, does workout (sometimes!) after the lab, and most of all she sings a lot (loudly)!

In her free time, she loves to cook, listen to music and watch movies.


Name: Peter Mosen
Position: PhD student
Special skill: Making noise

Peter studied Biotechnology with a major in Biomedical Science and Technology at Mannheim University of Applied Sciences. Due to his early interest in post-translational protein modification and protein expression patterns he quickly encountered LC-MS-based proteomics. As a research student at the German Cancer Research Center (DKFZ), Heidelberg and University of Washington, Seattle, USA he gained first experience in the field of untargeted proteomics. In summer 2016 he joined the Winter Lab and started his Ph.D. Now he is developing MRM-assays for targeted proteomics applications, further expanding the methodological repertoire of the Winter Lab. Besides all the MS-work, in his leisure time he is doing sports.

Name: Gishnu Harikumar Parvathy 
Position: M. Sc. student
Special skill: The silent guy

Gishnu – or Gish, as he prefers to be called, did his bachelor’s in University of Kerala, India, in Human medicine. After having worked in the division of Emergency Medicine for a couple of years, he switched his interest to basic sciences and immunology, which took him to Bonn where he is presently doing his master’s in Medical Immunosciences and Infection offered by the Excellence cluster ImmunoSensation. He has devoted considerable time after his medical studies working with NGOs like Lions Clubs International, volunteering to provide medical care in underserved areas at his home back in India. He is curious about how the different intracellular pathways interact in the dynamic environment of the cell, including- but not limited to- immune response, which landed him a thesis opportunity to study aspects of lysosome biology in the Winter lab. He is rather a quiet person, but do not mistake that for being not fun loving. He would not miss a chance to go out drinking or having food with his colleagues and friends.  If he is not in the lab, he would probably be walking in the woods or sleeping under a tree in the park, which is kind of his favorite hobby.
