Thomas Rossi is joining our lab as a postdoc to work on ultrafast optical and X-ray spectroscopy of photovoltaic nanomaterials. He received his PhD from the EPFL in the group of Majed Chergui where he worked on charge-carrier dynamics in metal oxides and hybrid lead perovskites. We are excited about his arrival and welcome him to our group!

Omid, Allan, Ryan, Eric and Frank were able to find the exact temporal overlap between laser and electron pulses. The difference image movie shows how a short (~200 fs) laser pulse generates a plasma at the edge of a copper grid, which deflects the electron pulse (shown as a bright/dark fringes). This is the final major milestone in the DETEM development. Almost ready to do real experiments!
