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: Norbert Rösel
Position: Technichian
Special skill: Master of everything

After working for almost 30 years in the IBMB as technician Norbert started the Winter Lab together with Dominic. He has longstanding experience in a broad range of biochemical and molecular biology techniques and knows every corner of the institute. In his working hours Norbert is helping the group members solving every problem in the lab and in his free time he continues helping them with private issues. If you need any help, call for Norbert!


Name: Robert Hardt
Position: Post Doc
Special skill: Thinks and talks fast

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: Alireza Dehghani
Position: PhD student           
Special skill: The fractionator      

Originating from Iran, Alireza joined the Winter Lab as intern in 2014 and was later upgraded to a Ph.D. student. As a part of his Ph.D. project, Alireza developed a new workflow for conducting large-scale phosphoproteomics experiments. Later, he applied this method to investigate phosphoproteome changes in altered cholesterol metabolism. Although doing a PhD is a 24/7 job, he still manages to do some extracurricular activities in between, such as Crossfit and learning German.


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)!


Name: Srigayatri Ponnaiyan
Position: PhD student
Special skill: -

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 Ph.D. 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: PhD student
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 Ph.D. in the Winter Lab. She is working on Niemann-Pick Disease Type C investigating lysosomal proteins related to cholesterol metabolism by mass spectrometry 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 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: Jasjot Singh
Position: PhD student
Special skill: The crosslinker

Being part of an international study programme in Biotechnology (University of Bremen) Jasjot finished his B.Sc. at the beginning of 2016 with a major in Industrial Biotechnology. Being a passionate traveller, he extended his studies with courses in Biomedicine (Sydney, Australia) and conducted an internship in the field of cell culture (Manchester, Great Britain). As part of his M.Sc. studies he conducted a project semester in the field of mass spectrometry at Sanofi (Frankfurt) which led him to the Winter Lab in the beginning of 2017. Jasjot works on lysosomal membrane proteins, investigating them with mass spectrometry. If he is not in the lab, you will find him in the gym next door lifting weights.


Name: Elham Pourbarkhordari
Position: PhD student
Special skill: Mice whisperer

Elham came to Germany from Iran in 2016 and started a Master's program in Life Science Informatics at the University of Bonn. Before, she already obtained a Bachelor’s and a Master’s degree in Biology and Clinical Biochemistry, respectively, in Iran. She is working in the Winter Lab as a student assistant helping the other members of the group with biochemistry and molecular biology experiments.


Name: Asisa Muchamedin
Position: M.Sc. student
Special skill: The dancer

After Asisa’s apprenticeship as a biological technician assistant (BTA) at Rheinische Akademie Köln, she started studying biology at the University of Bonn. For her project and bachelor thesis she joined the Winter Lab this year. She is working on a lysosomal membrane protein doing cell culture, performing enzyme assays and western blots. When time is left she likes to dance, do sports and gardening.
