cryoDrgn is the software she developed during her PhD to model continuous heterogeneity in cryoEM data. She uses a combination of coordinate MLP and variational autoencoders to do so. Listen in if you'd like to know more about what that means! We also touch on some of the details that speed up the training of the neural network that never quite fit into normal academic talks, including the use of the Hartley transform. No cryo2go pod is complete without some time spent on career trajectories, and Ellen's is quite interesting... listen to the end to hear us riff a bit on academia vs. industry : )]]>https://api.spreaker.com/episode/47681204Sat, 27 Nov 2021 19:05:46 +0000Benjamin HimesIn this episode, Ellen sits down with me to talk all things cryoDrgn ❄️🐉 Full transcript available at (https://github.com/bHimes/cryo2go/tree/main/transcripts/2020_EllenZhong_cryoDrgn) cryoDrgn is the software she developed during her PhD to...

This interview was recorded in June 2020 amid escalating calls for police reform and social justice in a country that has a long history of racial inequity. In the next episode, part II, we talk about how and when scientists should get involved in issues that many of us, myself included, shy away from.

Between publishing 13 papers in 2020 and locking down an Assistant Professorship at Stanford starting summer 2021, I count myself luck that Christopher made time to sit down and talk with me.

Phase plates offer a potential solution, but have been hampered by difficulty in use (Zernike phase plate) and loss of signal due to additional inelastic scattering (Volta phase plate)

Scwartz et al. demonstrate the use of very intense (the most intense!) laser light to induce a selective phase shift enhancing image contrast in moderate energy (80 KeV) electrons.
