Past Retreats: 2016 Speaker Profiles

Keynote Speakers

Eric Betzig, PhD

After obtaining a BS in Physics from Caltech, Dr. Eric Betzig moved to Cornell, where his thesis involved the development of near-field optics—the first method to break the diffraction barrier in light microscopy. Dr. Betzig then became a PI at AT&T Bell Labs in Murray Hill, NJ, where he further refined the technology and explored many applications, including high density data storage, semiconductor spectroscopy, and superresolution fluorescence imaging of cells. In 1993, he was the first to image single fluorescent molecules under ambient conditions, and determine their positions to better than 1/40 of the wavelength of light. Tiring of academia, Dr. Betzig then served as VP of R&D in his father's machine tool company, developing a high speed motion control technology based on an electrohydraulic hybrid drive with adaptive control algorithms. Commercial failure of the technology left him unemployed and looking for new directions. This search eventually culminated in the invention and demonstration of the superresolution technique PALM by himself and his fellow unemployed colleague and Bell Labs expatriate, Harald Hess. Since 2005, Dr. Betzig has been a Group Leader at HHMI’s Janelia Research Campus, developing new optical imaging technologies for biology.


Jorge Cham, PhD

Dr. Jorge Cham was born and raised in the Republic of Panama. He obtained his BS in Mechanical Engineering from Georgia Tech and his MS and PhD in Mechanical Engineering from Stanford University (specializing in Robotics), where he started drawing the comic strip “Piled Higher and Deeper” or “PHD”. He was subsequently an Instructor and Research Associate at Caltech from 2003-2005, where his work focused on developing “Smart” Neural Implants. He has published and presented nationally and abroad on his Robotics and Neural Prosthetics research.

Piled Higher and Deeper is a unique comic strip about life (or the lack thereof) in academia. Often called the Dilbert of academia, PHD has appeared in the Stanford, MIT, Caltech, and Carnegie Mellon newspapers among others, and it is published online where it receives over 7 million page views a month from over 1000 universities and colleges worldwide.

Since 2005, Jorge Cham has delivered over 300 invited lectures at universities and research centers worldwide, with audiences of a few dozen to a few thousand.

Fellow Speakers

Alejandro Alvarez-Prats, PhD

Dr. Alejandro Alvarez-Prats received his B.S. in Chemistry at U.N.E.D. in Madrid, Spain. During his college years, he attended several conferences at the Medical School of Universidad de Las Palmas de Gran Canaria (ULPGC), where he developed a special interest in research related to the elucidation of basic mechanisms involved in kidney diseases using different animal models. Once he finished his undergraduate degree, he was awarded a national fellowship which allowed him to enroll in a Ph.D. program at ULPGC. This program, entitled “Advances in Internal Medicine,” was specifically focused on Renal Physiology, and its main goal was to shed light on the pathophysiology of chronic kidney disease (CKD). After defending his Ph.D. thesis, he was accepted at the NIDDK to work on two short-term projects related to the implications of CD36 scavenger receptor and TLR4 on the progression of CKD. Upon completion of those projects, Dr. Alvarez-Prats joined NICHD as a postdoc under the supervision of Dr. Tamas Balla, to work on understanding the role of phosphatidylinositol 4-kinase type IIIα (PI4KA)—enzyme responsible for the generation of PI4P, a phophoinositide involved in the regulation of almost all aspects of cellular physiology—within the mammalian context. At the moment, Alejandro is focused on studying the role of PI4KA on the Peripheral Nervous System, since it is one of the most advanced projects he is currently developing in the Dr. Balla lab.


Maria Bindu Bagh, PhD

Dr. Maria Bindu Bagh is a Research Fellow in the laboratory of Dr. Anil B. Mukherjee, Section on Developmental Genetics (SDG), NICHD. She received her Ph.D degree in Physiology from University of Calcutta, India in 2011 under the mentorship of Dr. Sasanka Chakrabarti. Since joining NICHD in 2011, she has been working on a research project to understand the molecular mechanism(s) of a group of childhood neurodegenerative lysosomal storage disorders (LSDs) called neuronal ceroid lipofuscinoses (NCLs), commonly known as Batten’s disease. The primary area of her research is lysosomal acidification and storage dysfunctions, protein sorting and trafficking. Her initial research with other colleagues demonstrated a common link between two lethal LSDs infantile NCL (INCL) and congenital NCL (CNCL). Currently, she is elucidating the mechanism in detail by which lysosomal acidification is disrupted in a Cln1-/- mouse model for INCL. Her work may also lead to the understanding of common mechanistic pathways of lysosomal acidification defects in other common neurodegenerative disorders like Alzheimer’s and Parkinson’s disease.
