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 PhD 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 PhD 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: Post Doc
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 PhD 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)!

 



Name: Srigayatri Ponnaiyan
Position: PhD student
Special skill: Master of Microscopy 

Gayatri obtained a Master’s degree in Biomedical Science from Bharathidasan University, India before she joined the Winter Lab in 2015 with an Indian National Overseas Scholarship. Her PhD thesis work is focused on investigating the mechanism of lysosomal phosphatases and optimizing the isolation of lysosomes applying proteomics and molecular biology techniques. In her free time. Gayatri loves to go shopping, reading novels and watching Korean TV series.

 



Name: Fatema Akter
Position: Post Doc
Special skill: Queen of cell culture

Fatema is from Bangladesh where she obtained a degree as Doctor of Veterinary Medicine (DVM) as well as a Master’s in Pharmacology from Bangladesh Agricultural University (BAU). Since 2015, she is on study leave from her position as Assistant Professor with a scholarship from the German Academic Exchange Service (DAAD) to do her PhD in the Winter Lab. She finished her PhD. at the end of 2019 and stayed as a PostDoc. Currently, she is working on Niemann-Pick Disease Type C investigating lysosomal proteins related to cholesterol metabolism by mass spectromety based proteomics. 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 PhD 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.
