PhD-Program

The PhD program „Epidemiology and Clinical Research“ is a three-year, structured and internationally oriented doctoral program. Within the University Alliance Ruhr, the Institute of Medical Informatics, Biometry and Epidemiology (IMIBE) of the University Medicine Essen, the Department of Mathematical Statistics and Biometric Applications of the Technical University Dortmund, the Department of Medical Informatics, Biometry and Epidemiology and the Institute of Prevention and Occupational Medicine of the German Social Accident Insurance of the Ruhr-University Bochum are involved in the PhD program.

Goals

The program is designed to enable doctoral candidates to independently plan, conduct, analyze and publish studies on epidemiological and clinical issues (early detection, diagnosis, therapy and prognosis), taking into account Good Epidemiological Practice (GEP) and Good Clinical Practice (GCP). With the dissertation, the doctoral candidates prove that they achieve results through independent scientific work that serve the further development of the epidemiological field and clinical medicine.

Contents

The three-year doctoral program includes the integration into an own research project and an accompanying program designed for two years, which comprises a total of at least 300 teaching units (LE) of 45 minutes each. 263 units are compulsory and selectable modules. 37 LE can be freely chosen and are used to form focus competencies in epidemiology. The courses are offered as block courses in module form as 3-day or weekly courses. This means that the different knowledge, skills and abilities enabling the dissertation are acquired in complementary courses that build on each other. In 2 weeks per semester in each of the 1st and 2nd years of study, courses are held at the IMIBE/University Hospital in Essen. During the doctoral studies, presence at the IMIBE/University Hospital in Essen is only required for the courses and the 3-day RUHR School.

Among others, the following mandatory modules are part of the PhD program:

At the Ruhr School, guest lecturers offer interesting topics in the fields of epidemiology and clinical research.

During the PhD program, the PhD students will be accompanied by two supervisors.

The third year of the PhD program is used to finalize the dissertation. Upon successful completion of the PhD program, the Medical Faculty of the University of Duisburg-Essen awards the academic degree „Doctor of Philosophy (PhD)“.

The teaching language is English.

PhD- Students

Deborah Canales-Romero

Deborah Canales-Romero received her bachelor’s degree in Psychology in 2008 at the University of Monterrey, in Mexico. She worked as a forensic psychologist for a number of years before deciding to make the leap into academia by pursuing a Master’s degree in Research Methods in Psychology, which she finished in 2016 at the University of Southampton (UK). Since then, she continued working in academia and published a paper along with her supervisor about the COVID-19 pandemic lockdowns and its effects on the well-being of German families.

Deborah’s current research focuses on sexual behavior, specifically, the impacts of different conceptualizations of Compulsive Sexual Behavior in the levels of stigma in different spheres of interaction, namely: social, health and legal sectors. Additional variables to be manipulated are gender and neurobiological explanations for compulsive sexual behavior. This is a DFG-funded, three-phase project carried out at the Institute for Forensic Psychiatry and Sex Research of the LVR-Uniklinikum Essen.

Anne Lotz

Anne Lotz studied statistics at the TU Dortmund with a focus on Biometrics. Since 2005, she works in the competence center of epidemiology at the Institute of Prevention and Occupational Medicine of the German Social Accident Insurance (IPA), which is an Institute of the Ruhr University Bochum (https://ipa-dguv.de). Anne Lotz analyzed the association between workplace exposures and health effects in a variety of epidemiologic studies (ORCID https://orcid.org/0000-0002-8715-0743). Her recent research focuses on the analysis of left censored variables. Censored variables occur for example when measurement methods are not sensitive enough to quantify low-exposures correctly and one or more measurements can only be characterized as being less than a limit of detection. As exposure limits decrease and methods for exposure reduction improve these kinds of datasets might occur more frequently. In her first project in context of her PhD thesis Anne Lotz will look at possibilities to extend the method of Bland-Altman to censored variables.

Sarah Knispel

Sarah Knispel finished her university degree in medicine in 2012. Then, she started her clinical education and finished her dissertation during the first year of her residency. Supported by the supervising tutor, the dissertation resulted in a publication and was awarded with the Klaus-Dieter-Schulz-Versorgungspreis 2013. Since oncology has always been the focus of her interest, her research activities since finishing her dissertation are concentrated on melanoma. Currently, she is involved as a subinvestigator in several clinical phase I-III studies on patients with melanoma. In cooperation with consultant doctor Lisa Zimmer, she launched a retrospective multicenter analysis of patients with high LDH addressing the question of sequential therapy of immunotherapy and targeted therapy in patients with high LDH as these patients belong to a cohort with an especially high medical need.

Her research project for the PhD program is an explorative analysis addressing the questionable interactions between stress and depression and the immune system in melanoma patients. The activation of the immune system by PD-1 blockade is the most progressive therapeutical option in the field of dermatooncology and influence of stress on outcome parameters is insufficiently analyzed. The project is to be performed in collaboration with the department of medical psychology Essen (Prof. Schedlowski).
