Contact: dominic.winter[at]uni-bonn.de

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 Support Specialist

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 lover.

Name: Anne Sanner
Position: PhD student 
Special skill: The Optimist

Anne studied Bological Sciences in Münster and Cologne before she joined the Winter lab for her Ph.D. in November 2019. In the course of her studies, she also spent some time abroad in Canada (Montréal) to investigate cystic fibrosis, and in Berlin (Bayer Health Care), to work in the field of in vitro oncology. Her master thesis was completed in the CECAD in Cologne, where she worked with mass spectrometry. In her PhD, she focuses on TFEB and its isoforms, as well as the establishment of mass spectrometric methods. In her time off, she likes to travel, spend time with her friends and to paint.   

 



Name: Pathma Muthukottiappan
Position: PhD student 
Special skill: The Duracell

Pathma started her Master’s program at the University of Bonn in 2017. She joined the Winter lab as a student assistant in 2018, and then extended to do her Master’s thesis. Afterwards she successfully applied for a scholarship at the Jürgen Manchot Stiftung, which allowed her to carry on with her doctoral studies. She investigates the composition of lysosomes by mass spectrometry based proteomics. As a hobby, she cooks, and reads.    

 



Name: Sara Bonini
Position: PhD student
Special skill: The Pastry Chef

Sara comes from Italy, she took her Master degree in Pharmaceutical Biotechnology at the University of Perugia. She started with an Erasmus+ program at Winter lab in Bonn and now she is continuing her experience as PhD student. She investigates the response of the lysosomal proteome to changes in cellular nutrients. Her hobbies are cooking, reading books and watching old movies.  

 



Name: Yannic Hackenberg
Position: MD student
Special skill: The Good Doc

Yannic is our medical student and is doing his doctors thesis now in the lab. He started studying dentistry in 2016 and moved over to medicine in 2019 where he came in contact with the lab. His aim is to transfer our research on the human lysosomal proteome to lysosomal storage diseases and neurodegenerative diseases. When Yannic is not at UKB or in the lab, he loves to travel, run marathons, play football and steal food from the group members. 

 


  

Name: Dhriti Arora
Position: PhD student
Special skill: Jack of all trades

Dhriti comes from India, she performed her Bachelor’s studies in Biochemistry at the University of Delhi, India. Later in 2019, she came to Germany to perform a Master’s in Biochemistry at the LIMES-institute of the University of Bonn. During a rotation in the Winter lab, she discovered her growing love for mass spectrometry based projects and research and consequently decided to stay for her Master’s thesis. Seeing her fellow colleagues work on this technique,
she also wanted a topic for her thesis which involves some hands on with mass spectrometry. Now she is working on the characterization of the human lysosomal proteome by mass spectrometry. When Dhriti is not in the lab she likes to hang around with friends and to play table tennis.
