Recovery of missing single-cell RNA-sequencing data with optimized transcriptomic references
Allan and Yuki's work on improving the accuracy of scRNA-seq has been published in Nature Methods! Their paper is the result of a several-year effort to build a computational framework to improve cellular profiling resolution through the optimization of reference transcriptomes. This is an exciting study that saw a dramatic increase in the number of genes detected per cell, revealing previously "invisible" cell types and gene expression.
Congratulations to Elin for graduating from Caltech!! She was selected as an awardee of the prestigious 2023 Richard P. Schuster Memorial Prize. This prize recognizes her excellent undergraduate work and thesis in our laboratory. Good luck on the next position!
Jacob's Party in Malibu
Our lab research technician, Jacob's farewell party was held at the beach in Malibu with the great sunshine. Everyone enjoyed meals and hiking. We encountered sealions and a whale near the beach.
Lab Members enjoy a Thanksgiving Party
We celebrated Thanksgiving with an awesome feast and various drinks.
Sensory representation and detection mechanisms of gut osmolality change
Congratulations, Takako and Tongtong. Their work has been published in Nature. This study identified the site and mechanisms of gut osmolality sensing for thirst regulation. We provide another piece of data to understand how our body and brain work together to maintain internal environment.
Oka Lab Celebrates Thanksgiving
Thanksgiving at the Oka household is now an annual tradition! Yuki and Mari again graciously hosted the lab at their home for a fabulous meal!
Oka Lab Receives New Funding from NIH and the Caltech Heritage Medical Institute
We appreciate essential new supports from NIH and the Caltech Heritage Medical Institute. Yuki is now appointed as an investigator of HMRI.
Another Graduate from the Oka Lab -Takako Yamamoto
Congratulations to Takako for her new position at Niigata University in Japan as an Assistant Professor! She is a master of surgery and completed a very nice study about peripheral sensory signaling. We are sad to see her leave, but could not be more excited for her in pursuing her newest chapter
A New PI from the Oka Lab - Prof. Allan-Hermann Pool
Congratulations to Allan for becoming a new PI! Allan will open his laboratory at UT Southwestern this November. He will use transcriptomic and circuit technologies to uncover the mechanisms behind pain and analgesia! Allan will be sorely missed, but we could not be more excited for him and wish him the best of luck in his newest endeavor!
Oka Lab Malibu Beach Trip
After a long lockdown period, we were finally able to head out to Malibu for famous lobster rolls and a day of beach games!
Zhe Yang Receives Postdoc Scholarship
Congrats to Zhe for receiving Caltech divisional postdoctoral scholarship awards! We appreciate the generous support from the Division of Biology and Biological Engineering here at Caltech!
All Things Considered - NPR News Feature
Yuki joins reporter Jon Hamilton on popular NPR news series, All Things Considered, to discuss Allan and Tongtong's findings from their recent publication in Nature, The cellular basis of distinct thirst modalities.Read the transcript or have a listen.

Yuki dicusses Allan and Tongtong's recent Nature publication, The cellular basis of distinct thirst modalities, in a feature in Caltech news. Click to read the full article!
The cellular basis of distinct thirst modalities
Allan and Tongtong's paper in collaboration with UC Berkeley is now published in Nature. Congratulations to them both! This paper demonstrates that thirst is not a simple perception. Rather, different types of thirst are mediated by unique neuron classes in the brain.
Oka Lab Celebration
2020 has been challenging and anxious year to say the least, but despite this, many of our lab members have accomplished amazing things within the past few months. Unfortunately with the pandemic, we weren't able to meet up for each new accomplishment until recently. With this, we will soon say farewell to one of our first graduate students to join our lab, Sangjun Lee, and our long time lab manager, Brittany Ho. We celebrate Yameng Zhang joining our lab, as well as Allan's work being accepted for publication! Stay tuned to find out more details! Glad to see everyone from Oka Lab is thriving!
Sangjun's Successful Defense
After years of hard work, Sangjun has successfully defended his thesis work unveiling the neural basis of sodium appetite. Congratulations Dr. Sangjun Lee!
Yuki's Tenure Granted
Congratulations to Prof. Oka for being promoted to a full professor! The lab will work even harder to contribute to neuroscience!
Sloan Research Fellow
Congratulations to the lab for winning the Sloan Research Fellowship!
