Jan Michael Schuller

Group Leader, Mentor, CryoEM Maniac and Father

Jan's motivation is to understand biological CO2 fixation and to combine the obtained knowledge with synthetic biology and biotechnological methods to help combat man-made climate change. 

He is writing grants, papers, sits in committees and video conferences... PI stuff. Sometimes he interferes with peoples CryoEM processing.

In his free-time he is mainly a proud father of two kids. A 5-year old little ballerina, princess and his 1-year old little car fanatic.



Anuj Kumar

PhD Student

Anuj received his BS-MS from IISER Mohali, India. His goal is to decipher the structural dynamics of protein complexes that play an important role in bioenergetic processes. To do this, he uses a comprehensive combination of techniques, including cryo-EM and molecular dynamics simulation. 


Before he came to the lab, he worked at the German Electron Synchrotron Hamburg, and at the Kavli Institute Of Nanoscience at TU Delft.  


When he is not in the laboratory, he likes to spend his time reading books.



Yat Kei Lo

PhD Student

Can we combat global warming by turning CO2 into fuel, fabric, plastic, or any commodity efficiently? Yat Kei is curious about how organisms capture CO2 and how we can use their amazing ability to build a green future.


After getting his MSc in LMU München, Yat Kei is currently investigating mechanisms of various prokaryotic carbon concentration mechanisms (CCM) – extraordinary adaptations driving carbon fixation using structural, biochemical, and molecular techniques. He aims to translate his finding into an efficient synthetic carbon-harnessing machinery. He believes learning from the nature is the key to a sustainable future.


Tristan Reif-Trauttmansdorff

PhD student

After completing his master studies in Berlin, Tristan came to Marburg to work with a variety of strictly anaerobic microorganisms for his PhD. From the oxygen-free cultures to the implementation of native purification techniques, his ultimate goal is the isolation and analysis of molecular machines involved in energy conservation - in both acetogenic bacteria and methanogenic archaea.



Fidel Ramírez-Amador

PhD student

Fidel obtained his biotechnology background at the IPN and UNAM in Mexico. His current projects revolve around the methanogenesis in archaea. Solving the structure of these anaerobic complexes should help unravel their activity mechanisms and interactions.



Lena Schmück

PhD student

Lena investigates the cyanobacterial Sulfur Mobilization Machinery (SUF). This is a very interesting mechanism, which assembles and transfers Iron-Sulfur-Clusters into target proteins. She wants to learn how a metallic cluster is formed within this kind of complexes as well as understand the function of its puzzling ATPase activity.



Sophia Paul

Master student

Sophia completed her Bachelors in Biochemistry and Molecular Biology in Jena. There after, she joined Philipps University Marburg for a master's degree with a focus on protein biochemistry and structural biology. During her tenure as a master's student, she did various internships, including one in which she was trained on cryo-EM/ET in the Netherlands. She has gained experiences with projects demanding molecular biology and protein expression/purification. For her master thesis, she is working on cultivating anaerobes and purifying exciting proteins that are bioenergetically relevant.
