Insertable, Implantable and Wearable Micro-optical Devices for the Early Detection of Cancer
Optical imaging tools image over a range of scales from macro- to nanoscopic resolution and can provide molecular sensitivity and cellular level resolution. Developments in the field of optical imaging will be useful in informing diagnosis, prognosis and therapy, and for guiding biopsies for multiparameter molecular analyses.
Christopher Contag is a Professor in the Departments of Pediatrics, Radiology, Bioengineering and Microbiology & Immunology at Stanford University, and a member of BioX program for interdisciplinary sciences, and the program in Immunology. Dr. Contag is the Associate Chief of Neonatal and Developmental Medicine, director of Stanford’s Center for Innovation in In Vivo Imaging (SCI3) and co-director of the Molecular Imaging Program at Stanford (MIPS) and the Child Health Research Institute. Dr. Contag is a pioneer in the field of molecular imaging and is developing and using imaging approaches aimed at revealing molecular processes in living subjects, including humans, and advancing therapeutic strategies through imaging.

Polaritons in Two-dimensional Electron Systems
Cavity-polaritons have emerged as an exciting platform for studying interacting bosons in a driven-dissipative setting. In this talk, I will present cavity spectroscopy of gate-tunable monolayer MoSe2 hosting a degenerate electron gas and exhibiting strongly bound exciton-polaron resonances, as well as non-perturbative coupling to a single microcavity.
Atac Imamoglu graduated with PhD from Stanford University in 1991. His PhD thesis was on the proposal and first demonstration of electromagnetically induced transparency. He joined the the University of California Santa Barbara from 1993 and 2002. In 2003 he moved to ETH Zurich as a Professor of Physics where his works focuses on quantum optics and condensed matter physics. He is the recepient of an IEEE Quantum Electronics Award and The Optical Society Charles Townes Award.

Ultrafast Solid-state Lasers: A Success Story with no End in Sight
This talk will review and give an outlook on ultrafast solid-state lasers based on SESAMs for passive modelocking. The thin disk laser geometry for efficient heat removal is currently the most successful approach for power scaling of diode-pumped ion-doped solid-state and semiconductor lasers. Different gain materials, different performance parameters and different modelocking dynamics require different SESAM parameters. Novel optically pumped semiconductor disk lasers with fully integrated gain and absorber layers (i.e. MIXSEL) give full wavelength flexibility, simple linear cavities and can easily be operated in a dual comb mode. These lasers enable many application ranging from precision micromachining, frequency metrology and nonlinear microscopy.

Gravitational Wave Detectors of the Future: Beyond the First LIGO Discoveries
In February 2016, scientists announced the first ever detection of gravitational waves from colliding black holes, launching a new era of gravitational wave astronomy and unprecedented tests of Einstein’s theory of general relativity. Searching for fainter or more distant sources requires ever greater sensitivity for the laser interferometric detectors that made these first discoveries. I will describe current efforts to improve the sensitivity of gravitational wave detectors and their prospects for future discoveries.
Nergis Mavalvala, Marble Professor of Astrophysics at MIT and a 2010 recipient of a MacArthur “genius” award, is a physicist whose research focuses on the detection of gravitational waves. She is a longstanding member of the scientific team that announced the first direct detection of gravitational waves from colliding black holes by the Laser Interferometer Gravitational-wave Observatory. Mavalvala has also conducted pioneering experiments on generation and application of squeezed states of light, and on laser cooling and trapping of macroscopic objects to enable observation of quantum phenomena in human-scale systems. Mavalvala received a B.A. from Wellesley College and a Ph.D. from MIT. She was a postdoctoral fellow and research scientist at the California Institute of Technology before joining the Physics faculty at MIT in 2002.
