Dr. Erjuan Guo: Integrated complementary circuits based on organic permeable dual-base transistors: The lack of appropriate vertical-channel dual-gate organic thin-film transistors has limited the development of organic complementary circuits. In this project, organic vertical-channel permeable dual-base transistors are proposed and used to create integrated complementary inverters and ring oscillators. The vertical dual-base transistors enable switching voltage shift and gain enhancement. The inverters exhibit small switching time constants at 10 MHz, and the seven-stage complementary ring oscillators exhibit short signal propagation delays of 11 ns per stage at a supply voltage of 4 V.

Dr. Marta Urbańska: Single-cell mechanical phenotyping across timescales and cell state transitions: The importance of mechanical properties of cells in processes such as tissue development and cancer metastasis has become undeniable. Hence, there is a pressing need for establishing robust methods to measure and control cellular stiffness. In my thesis, I consolidated microfluidics-based methods for high-throughput single-cell mechanophenotyping, discovered changes in mechanical phenotype during cell (de-)differentiation along the neural lineage, and identified candidate genes that can be used to tune the mechanical properties of cells. These contributions push the frontiers of single-cell mechanical phenotyping and lay ground for controlling cell stiffness on demand to enable cellular functions or prevent pathologies.
