shareholder & ceo


Quirin Graf Adelmann was born in Munich and grew up bilingual, spending his youth in both Germany and France. He pursued a law degree at Humboldt Universität Berlin and completed his studies with the Staatsexamen (government-recognized exam). During his studies he founded the soccer club “FC Karlshorst 1995 e.V.” with 22 youth teams and close to 700 members.

Graf Adelmann went on as authorized representative and finally CEO of Herbst Motorsport, the largest car parts dealer (retail and distribution) in Northern Germany. He restructured the company, optimized processes, acquired new customers and increased profitability significantly.

From 2008, Graf Adelmann focused on real estate when he became the CEO of German operations for a London-based family investment office. Despite the financial crisis, Graf Adelmann successfully developed a new office building in Frankfurt in prime location, a TV production company in Köln and transformed an office building in Berlin Mitte into a large-scale Hotel (>120.000 guest-nights per year). He developed and invested own capital in Berlin residential projects such as "Floragärten", "Komponistengärten" and "Leo Urban Living" (combined 543 units, 44.000 sqm net residential space).

Graf Adelmann also participates in and leads many additional endeavors in the fields of culture, healthcare and FinTech startups. His portfolio includes the famous DDR Museum Berlin, the multimedia exhibition nineties berlin, a Berlin-based nursing service, Polyteia (big data for smart city) and Arttraktiv (24/7 rehearsal rooms for 1.000 musicians).

Dr. Lena Wedeken

lab manager


Lena studied human biology at the Philipps-University of Marburg and then joined the group of Professor Karl-Heinz Klempnauer at the Westfälische Wilhelms-University of Münster where she obtained her PhD in biochemistry/molecular biology in 2011. Her PhD research project was focused on the tumor suppressor protein Pdcd4 and its involvement in translational regulation.

Following, Lena moved to Duarte in sunny Southern California for a postdoc at the Beckman Research Institute of City of Hope in the group of Professor Hsun Teresa Ku where she established serum-free culture conditions for primary human and murine adult pancreatic stem- and progenitor-like cells in a 3D culture system and studied the impact of compounds, growth factors, signaling pathways and donor characteristics on these cells.

Before joining CELLphenomics in 2020, Lena was Scientific Officer at the European Association for the Study of Diabetes (EASD) and its associated foundation. Lena has experience in a wide range of cell biology, molecular biology and protein biochemistry methods and techniques and in addition holds a project management certification.

Dr. Samantha Exner

project manager


After a gap year in New Zealand Samantha moved to Greifswald to study human biology. In 2013 she relocated to Berlin joining the group of Carsten Grötzinger in the department of gastroenterology at Charité - Universitätsmedizin Berlin. Since then her research focused on cancer and its targeted diagnosis and therapy. During her PhD Samantha worked on the validation of tumor-specific receptors and the preclinical development of cognate peptide-based ligands. These were optimized in respect of receptor specificity and affinity to act as molecular vehicles transporting contrast agents or therapeutics directly to the site of action. She successfully finished her thesis with the title “G protein-coupled peptide receptors as molecular targets in neuroendocrine tumors”.

Samantha is experienced with in vitro cell based assays as well as imaging and biodistribution analyses using near-infrared or radioactive probes. She worked on the establishment of primary cell cultures and PDX-models of NET origin and applied a wide spectrum of standard methods from molecular biology to protein biochemistry.

Dr. Jürgen Loskutov

staff scientist


Before joining the CELLphenomic's team in 2019, Jürgen Loskutov has studied Physiology at Saint Petersburg State University, Russia. In 2010 he joined the group of Professor Elena Pugacheva in West Virginia University, USA, to investigate the role of NEDD9 in breast cancer cell migration and invasion. In 2012 he was accepted into the "Cancer Cell Biology" PhD program at West Virginia University. There under the supervision of Professor Pugacheva he was investigating the association of the primary cilia loss with highly aggressive phenotype in glioblastoma. The aim of his PhD project was to uncover the molecular mechanisms underlaying the increase in proliferation upon loss of primary cilia and to establish if effected pathways can be targeted in glioblastoma. During his PhD he was also strongly involved in establishing new PDXs for WVU HSC PDX Core facility.

Alina Braukmann, MSc

screening expert



Before joining CELLphenomics in 2019, Alina has studied biology and anthropology at the Johannes Gutenberg-University in Mainz, Germany. In 2015, she earned her bachelor’s degree in biology at the Institute of Human Genetics at the Johannes Gutenberg University medical centre in Jennifer Winter's group. The aim of her bachelor thesis The Establishment of P19 Cells as a Neuronal Cell Model was to test and evaluate approaches for the differentiation of the embryonic carcinoma cell line P19. She compared these approaches in terms of practicability, efficiency and reproducibility resulting in a best-practice approach, which is since used as a SOP in her former group. In 2018, she earned her master’s degree in anthropology at the Institute of Pathology at the Johannes Gutenberg University medical centre in the group of Dr. Nils Hartmann. Here, she investigated mitochondrial DNA alterations of colorectal cancer from FFPE tissues by establishing and optimizing an automated NGS screening workflow for sequencing the entire mitochondrial genome.

Ulrike Pfohl, MSc

PhD candidate


Ulrike Pfohl finished her apprenticeship as Biology Laboratory Technician at Charité University Medicine Berlin before she started an internship in the genome biology group of Dr. Thomas Caspari in the School of Biological Sciences at Bangor University (UK). Here, she constructed mutant alleles of the S.pombe rad9 DNA damage checkpoint gene. 

Ulrike studied human biology at Ernst-Moritz-Arndt-University in Greifswald. She finished her Bachelor of Science in the field of pediatric oncology, in particular, she investigated the efficacy of a novel hydrolytic-activated prodrug of etoposide (ProVP-16 I) in neuroblastoma cells. Since 2016, she has a master’s degree in human biology. The aim of her master thesis was the analysis of murine stroma components in patient-derived xenograft (PDX) models of pancreatic cancer which she accomplished at EPO - experimental pharmacology & oncology Berlin-Buch GmbH in the group of Dr. Iduna Fichtner. In 2017, she started with her PhD thesis in the same company but now has moved on to pursue her research goals at the Department for Pathology at Otto-von-Guericke University in Magdeburg in cooperation with CELLPHENOMICS GmbH. She is generating CRISPR-engineered organoids of colorectal cancer to utilize them as in vitro models to investigate the effect of specific mutations on drug response.

Manuela Regenbrecht

MD candidate


Manuela studied human medicine at the Charité University Medicine in Berlin. She received her license to practice medicine in November 2014. Since 2015 she is working as a physician in the department of oncology and palliative care at the Helios Klinikum Berlin-Buch. Due to the sarcoma specialization of the department she had the opportunity to work in large part with patients suffering from sarcoma during her medical specialist training.

Since January 2018 Manuela acts as a Clinical Study Manager and MD candidate working on the establishment of patient-derived 3D cell cultures of sarcomas within the framework of the SarQma Study.

Prof. Dr. Reinhold Schäfer



Reinhold studied biology at Rheinische Friedrich-Wilhelms-University in Bonn. He received a PhD in biology in 1976. He did postdoctoral work at the Max-Planck-Institute of Experimental Medicine in Göttingen and at the Institute of Cell Biology (Tumor Research), the West German Cancer Center, University Hospital Essen. He became staff scientist and group leader at the Ludwig Institute for Cancer Research in Berne, Switzerland, in 1985 and was appointed head of the Division of Cancer Research, Department of Pathology, University of Zürich in 1988. He worked as Professor of Molecular Tumor Pathology at Charité Universitätsmedizin Berlin from 1996-2016. He coordinated the Berlin site within the German Cancer Consortium (DKTK) from 2012-2016. Currently, he is deputy director of the Charité Comprehensive Cancer Center and is working as researcher and advisor within the DKTK and fellow at the German Cancer Research Center (DKFZ) in Heidelberg.
