Lead OCRUG Book Club Session on Topic Modeling

This evening, I led the session on Topic Modeling in the book club of Orange County R Users Group (OCRUG). The session covered contents of chapter 5 (converting to and from non-tidy formats) and chapter 6 (topic modeling) of the book Text Mining with R. All of my teaching slides and exercise materials can be found here.

This is the first time I really look into Natural Language Processing (NLP) and it’s fun. Although my research doesn’t really need to apply NLP directly, I still found it promising especially for researchers in the field of life sciences. The burgeoning of explainable AI could make things easier for the general public to understand scientific results and NLP will play an important role in filling the gap. Maybe in one day, all patients could easily understand their brain health after brain scans via the excellent interpretation of a machine.

Host CNLM Panel ‘How Addiction Hijacks the Brain’

This evening, I hosted the CNLM ambassador’s panel “How Addiction Hijacks the Brain: What Animal Models Can Tell Us About the Neurobiology of Drugs of Abuse”. This panel features four UCI addiction experts Dr. Christie Fowler, Dr. Ariana Nelson, Dr. Jessica Childs, and PhD candidate Mitchell Farrell. This is the second panel hosted by CNLM Adult Outreach Committee and we have over 60 attendees from the Irvine community. Although the audience size in summer is smaller than during the school year, I really enjoyed facilitating the panel discussion, learned about neural mechanisms underlying drug addiction, and was deeply inspired by scientists who are determined to devote their lifelong career to improving people’s mental health.

Today, I presented my work on head direction signals in the human brain at this year’s annual meeting of the organization for human brain mapping (OHBM). The conference focuses on understanding the organization of the human brain using neuroimaging methods. At this conference, I learned about new fMRI data analyses methods and different perspectives on open science and publishing.

This afternoon, I gave a poster presentation of my latest findings of head direction signals in the human brain at spatial@ucsb.global2021 - the annual spatial conference hosted by the Spatial Center at UC Santa Barbara with a topic on “Spatial Data Science for a Sustainable Future”. I’m glad to share my fresh research findings with my UCSB colleagues in both geography and psychology.
