The group of Prof. Lemmer is looking for a PhD candidate for an exciting project in the field of Printed Photonics.
Project description:
Printed photonic components are one of the research topics at Light Technology Institute. Recently, the research group has succeeded in manufacturing e.g., microlenses and Bragg mirrors by means of digital inkjet printing. This opens up numerous research opportunities for novel sensor systems and applications in large-area optoelectronics, for instance displays and photovoltaic technologies. To strengthen our team, we are looking for a PhD student to start as soon as possible.
Doctoral position, limited to 3 years with a chance for extension. Funding will initially be provided by a fellowship from the Carl Zeiss Foundation through the Cluster of Excellence 3DMM2O.
Upon acceptance, the Doctoral Researchers will be part of the structured doctoral program offered by the HEiKA Graduate School on Functional Materials, which brings together Young Scientists in an interdisciplinary environment. The participating disciplines encompass chemistry, physical chemistry, physics, biophysics, biology, biomechanics, mechanical engineering, and electrical engineering.
Requirements:
Requirements for the application include a degree (MSc or equivalent) with above-average marks in in electrical engineering and information technology, materials science, process engineering, physics or related fields with excellent results. Furthermore, knowledge in the field of photonics, strong interest in experimental work (inkjet printing, optical characterization, etc.), strong analytical skills and structured, independent work styles.
Additional information about the research topics and requirements on the website of the Light Technology Institute. Further questions about the research projects should be directed to Uli Lemmer (uli.lemmer@kit.edu) directly.
Applications should be handed in only through our Application Portal. Please indicate the position you are interested in so we can make sure to evaluate your application accordingly. The following documents and data are required for your application:
- CV
- School and University (as applicable: Bsc, MSc, Doctorate) certificates
- Transcripts (BSc and MSc)
- Cover Letter
- Letter of Motivation & Abstract of Research Interest

The laboratory of Prof. Dr. Daniela Duarte Campos at the Center for Molecular Biology (ZMBH) is seeking a PhD student in the field of Optogenetic iPSC culture for cardiac tissue engineering.
Project description:
For participating in the ERC Starting Grant LIGHTHEART focused on the development of a new in vivo bioprinting technology to fabricate human cardiac muscle directly at the operating room.
Heart failure remains a leading cause of mortality worldwide taking an estimate of 16 million lives each year. Cardiac tissue engineering solutions that can improve the quality of life of those with advanced heart disease have proved challenging so far. Bioprinting is an exciting technology that holds promise to fabricate tissues and organs. Lab-grown engineered cardiac muscle requires at least four weeks to maturate in a bioreactor. In LIGHTHEART, an off-the-shelf solution will be developed for treating injured myocardium in vivo. An unconventional combination of bioprinting and optogenetics will be used to surgically fabricate engineered cardiac muscle directly at the patient’s heart.
The Bioprinting Lab investigates biofabrication technologies and biomaterials suitable for in vivo and in vitro tissue and organ engineering, and their impact on the structure and function of natural and synthetic living tissues.
Your task will be to establish and optimize culture protocols of human pluripotent stem cells (iPSCs) and iPSC-derived cardiomyocytes, as well as to analyse and characterize the expression of light-sensitive proteins. The work will involve a variety of techniques including but not limited to:
- 2D and 3D cell culture
- Molecular methods in 3D cell culture (CRISPR/Cas9, DNA/RNA arrays, qPCR, Western Blot, etc)
- Histology, immunochemical staining and imaging
- Flow cytometry, FACS
Funding:
We offer an international and attractive work environment in the Bioprinting Lab at the ZMBH. The salary is based on the TV-L scale (E13). The position is to be filled in with 25,675 hours/week (65%) for two years, with the possibility of extension. The position is available to start in September 2024.
Your profile:
- Master degree in Biology or Biotechnology
- Experience in human cell culture is mandatory
- Experience in iPSC and/or cardiomyocyte cell culture is a plus
- Experience with optogenetics is a plus
- Experience in 3D cell culture is a plus
- Excellent achievements and English language skills
- Motivation to work in an international environment as part of a team
Application:
Applications should be sent to Prof. Daniela Duarte Campos (dcampos@uni-heidelberg.de) in a single PDF-file that includes a letter of motivation, CV, copy of transcripts and name of 2-3 referees. We ask for your understanding that application documents received by post will not be returned.
Closing date for applications: July 31, 2024
Heidelberg University stands for equal opportunities and diversity. Qualified female candidates are especially invited to apply. Disabled persons will be given preference if they are equally qualified. Information on the application process and the collection of personal data is available at www.uni-heidelberg.de/stellenmarkt.
