Congratulations to Jeffrey Wang for getting accepted into the Mind, Brain, Computation and Technology graduate training program!

Dr. Jeffrey Wang has been accepted into the Mind, Brain, Computation and Technology graduate training program where he will be expected to engage as a contributing member of the community, attend center seminars and the annual trainee meetings, present his work to the community, and to take an active role in assisting with ongoing center events, or in developing new ways to strengthen and enrich the community.

For this program, Jeff had to pass through a competitive application process that involved essentially having to complete a second qualifying examination to demonstrate his knowledge and aptitude regarding quantitative techniques, and to defend his thesis proposal on defining a spatiotemporally resolved model for the physiological action of ketamine using ultrasonic drug uncaging. Congratulations, Jeffrey!

Collaboration with the NIH Nanoparticle Characterization Lab

In April 2018, the NIH/NCI Nanoparticle Characterization Laboratory (NCL) accepted our propofol-loaded polymeric perfluorocarbon nanoemulsions into their characterization and testing program, which is designed to promote the clinical translation of novel nanomedicines. These propofol-loaded nanoparticles  will now undergo their rigorous in vitro and in vivo evaluation. If these particles pass the NCL assays with acceptable results, we plan to apply for an investigatory license from the FDA for first-in-human trials to complete noninvasive functional brain mapping as part of neurologic and neurosurgical evaluations.

New bioRxiv preprint on a nanoparticle platform for ultrasonic drug uncaging

Congrats Qian and Jason! Their manuscript entitled “Polymeric perfluoropentane nanoemulsions are a versatile platform for ultrasonic drug uncaging” is currently available on the preprint server bioRxiv at https://www.biorxiv.org/content/early/2018/09/10/315044.

This work developed polymeric perfluoropentane nanoemulsion as a generalized platform for localized ultrasonic drug delivery. They showed that this nanotechnology platform can be used to encapsulate most hydrophobic drugs. The nanoemulsions have shown excellent ultrasound responsiveness and bioeffects for a wide variety of drugs, and demonstrated a stability that yields high potential for clinical translation for noninvasive ultrasonic drug uncaging in the brain and body.

Raag Received an ASCI 2018 Young Physician-Scientist Award!

Dr. Raag Airan, an Assistant Professor of Radiology (Neuroradiology), has received the American Society for Clinical Investigation 2018 Young Physician-Scientist Award. He will present his research at the AAP/ASCI/APSA Joint Meeting in Chicago, Illinois, April 20-22.

The ASCI Council Young Physician-Scientist Award recognizes physician-scientists who are early in their first faculty appointment and have made notable achievements in their research. With these awards, the ASCI seeks to encourage and inspire these physician-scientists through their participation in the Joint Meeting.

Congratulations, Dr. Airan!

Congratulations to Muna for winning a prestigious Stanford SCIT fellowship!

Dr. Muna Aryal has been named as a recipient of a Stanford SCIT fellowship! This is a prestigious training program for postdoctoral fellows working on novel and interdisciplinary solutions for cancer imaging. For her project, Muna will work collaboratively between the Dahl and Airan labs to develop a fusion of focused ultrasound, passive acoustic imaging (PAI), and PET imaging to determine a method to calibrate the degree of in vivo ultrasonic drug uncaging using nanodroplets. She will then apply this method in a large animal model, as a prerequisite to clinical translation. This work will build on her already amazing work on quantifying the efficacy of ultrasonic drug uncaging in small animals, and her PhD thesis work on ultrasound-mediated blood brain barrier opening for drug delivery.

Congratulations Muna!!
