    Felix Allum

    Postdoctoral Scholar, Photon Science, SLAC

    BioI am a Postdoctoral Scholar affiliated with the PULSE institute and the LCLS Laser Science Division. My research interests focus on the ultrafast photodynamics of isolated molecules in the gas phase, as studied by a range of techniques typically incorporating charged particle imaging, photoionization spectroscopy or diffractive imaging. I am also interested in developing new approaches to studying ultrafast photochemistry, through, for instance, the generation of broad bandwidth optical pulses and new data analysis techniques to extract additional information from rich and complex datasets.

    Prior to joining SLAC in October 2021, I studied for my PhD at the University of Oxford under the supervision of Mark Brouard. My doctoral research included a range of studies into ultrafast photodissociation dynamics using velocity-map imaging, both in a laboratory setting and at international FEL facilities.

  • Marwa Atwa

    Marwa Atwa

    Postdoctoral Scholar, Photon Science, SLAC

    BioMarwa Atwa is a postdoctoral scholar at Nanoscale Prototyping Laboratory (NPL), focusing on developing durable electrodes for hydrogen fuel cells. She got her Ph.D. in Chemistry from the University of Calgary in 2021 under the supervision of Professor Viola Birss, where she mastered different skills in both material science and electrochemistry fields. During her Ph.D. studies, she developed and tested highly active cathodes for hydrogen fuel cells based on novel nanoporous carbon films made from uniform and bimodal porous structures. Before joining the University of Calgary, Marwa received her M. Sc. And B. Sc. degrees in Chemistry from Suez Canal University, where her research focused on protecting low-carbon steel from corrosion in an acidic medium by applying various nanoengineered metal and alloys coatings using electroplating technique.
