Principal Investigator:

Anne Milasincic Andrews, Ph.D.



Anne Andrews, Ph.D., is Richard Metzner Endowed Chair in Clinical Neuropharmacology, and Professor of Psychiatry & Biobehavioral Sciences and Chemistry & Biochemistry at the University of California, Los Angeles. At UCLA, Andrews leads efforts in basic and translational research on anxiety and depression, and at the nexus of nanoscience and neuroscience. Andrews interdisciplinary research team focuses on understanding how the serotonin system and particularly, the serotonin transporter, modulate neurotransmission to influence complex behaviors including anxiety, mood, stress responsiveness, and learning and memory. Dr. Andrews was a guest of the White House during President Obamas announcement of the BRAIN initiative, which she helped to shape.

Dr. Andrews earned her B.S. in chemistry from the Pennsylvania State University and received her Ph.D. in chemistry as a U.S. Department of Education Fellow working at the National Institute of Mental Health. There, she was later a postdoctoral fellow and senior staff fellow. Andrews has been the recipient of an NIH Fellows Award for Research Excellence, an Eli Lily Outstanding Young Analytical Chemist Award, an American Parkinsons Disease Association Research Award, and a Brain and Behavior Research Foundation Independent Investigator Award. She is a member of the American College of Neuropsychopharmacology, a fellow of the Collegium Internationale Neuropsychopharmacologicum, International Society for Serotonin Research vice president, an advisory board member for the International Society for Monitoring Molecules in Neuroscience, and serves as Associate Editor for ACS Chemical Neuroscience.

Senior Scientists/Postdoctoral Fellows

Dr. Hongyan Yang


Dr. Yang earned a B.S. in Biology & Applied Electronics (1997) and a Ph.D. in Molecular Neuroscience (2002) from East China Normal University in Shanghai. Her doctoral work, titled Function of NMDA receptors in the development of the central auditory system, was carried out under the supervision of Prof. Xinde Sun. In 2002, she joined Prof. Liangyou Ruis group as a Postdoctoral Fellow in the Department of Molecular & Integrative Physiology at the University of Michigan. There, she studied the mechanisms of obesity and type II diabetes. In 2003, Dr. Yang joined the laboratory of Prof. Jill Becker in the Molecular & Behavioral Neuroscience Institute at the University of Michigan. Under Dr. Beckers guidance, she focused on investigating gender differences in drug abuse, rapid effects of estradiol in the brain, and sex chromosome effects in Parkinsons Disease. In 2011, she joined the laboratory of Prof. Andrews where she is currently investigating the influences of neonatal serotonin transporter disruption on adult serotonin system circuitry. Dr. Yang is also working on fast scan cyclic voltammetry to study serotonin system function in vivo.


Dr. Liane SLianelaughter


Liane Slaughter joins the Weiss and Andrews groups after finishing her Ph.D. in chemistry at Rice University under the guidance of Prof. Stephan Link. Her graduate work used correlated electron and optical microscopy to examine gold nanoparticles and their assemblies one at a time to reveal sensitive and otherwise unknown relationships between their geometries and their optical properties. Before her graduate studies, Liane earned her B.A. in chemistry from Cornell University. While she was there, she researched mesoporous metal materials with potential applications for fuel cells under the mentorship of Scott Warren, who was co-advised by Profs. Ulrich Wiesner and Francis Disalvo.  Lianes interests include self-assembly and patterning of molecules and nanoparticles on surfaces, single particle microscopy and spectroscopy, and understanding the consequences of molecular adsorption on the structural and electronic properties of their underlying surfaces.

Graduate Student Researchers

Brendan S. Beikmann


Brendan Beikmann graduated from Colorado State University in 2007 with a B.S. in Biology and minors in Chemistry and Biomedical Science. He is currently working as a Staff Research Assistant with Dr. Anne Andrews at UCLA while concurrently pursuing a Ph.D. in Neuroscience from the Pennsylvania State University. Mr. Beikmann's graduate research is focused on characterizing peripheral blood cells as biomarkers for predicting serotonin selective reuptake inhibitor antidepressant treatment efficacy in depressed individuals. This project is being carried out in collaboration with Professor Andrew Leuchter at UCLA. Using chronoamperometry, Brendan is also examining serotonin transporter function in peripheral blood cells from healthy individuals having immune system stimulation via a low dose of endotoxin. Professors Naomi Eisenberger and Michael Irwin, UCLA collaborators on this project, have found that brief immune stimulation induces transient depressed mood. Brendan also works on developing a flow cytometry-based assay for examining monoamine transporter function in platelets and peripheral blood mononuclear cells utilizing fluorescent substrates synthesized in the laboratory of Professor Sandra Rosenthal at Vanderbilt University.


Huan H. Cao


Huan Cao graduated summa cum laude in 2008 with a B.S. in Chemistry from Marshall University where he also minored in Mathematics and Physics. Mr. Cao carried out undergraduate research under Professor Michael Norton to develop strategies to attach DNA to Au nanostructures on Si substrates using dendrimer chemistries. Currently, he is a Ph.D. student in the Department of Chemistry & Biochemistry at UCLA. Mr. Cao works jointly between the Andrewss group and Professor Paul S. Weisss group at the California NanoSystems Institute. His graduate research is focused on developing advanced nanoscale surface chemistries for small-molecule neurotransmitter functionalized substrates. Together, he and Dr. Wei-Ssu Liao are using microfluidics to create multiplexed surfaces having different neurotransmitters tethered and addressed on a single substrate. In addition, they developed chemical lift-off lithography, a novel high-resolution chemical patterning method. These and other multiplexed platforms fabricated using microcontact insertion printing enable capture and sorting of neurotransmitter biomolecule binding partners, such as G-protein-coupled receptors, for structural and functional studies. Mr. Cao is currently a training fellow in the UCLA NeuroImaging Training Program (NITP) sponsored by the National Institutes of Health and was the recipient of an Incoming Graduate Student Award for excellence in coursework and teaching at the Pennsylvania State University, prior to relocating with Andrews and Weiss to UCLA. 


Nako Nakatsuka


NakoNako graduated from Fordham University with a BS in Chemistry and a minor in French in 2012 . She carried out undergraduate research under the mentorship of Professor Ipsita Banerjee and her bionanotechnology research focused on design, synthesis and assembly of peptide bolaamphiphiles for potential tissue engineering and drug delivery applications; using elastin and collagen functionalized peptide nanotubes as potential scaffolds for cartilage regeneration; generating soy-peptide hydrogels that encapsulate and release various drugs incited by pH environment. In addition, she explored specifically designed peptide sequences for cell penetration and examined the effect of size, charge and specific amino acid moieties for cellular penetration. Additional work involved gene therapy with siRNA bound microtubular networks, as well as biomimetic formation of gold, platinum and silver nanoparticles using specific peptide sequences. Nako's joint graduate research between Dr. Anne Andrews' and Dr. Paul Weiss' labs  focuses on developing nanoscale surface chemistry for small-molecule such as neurotransmitters, in addition to capturing multiple molecules on the surface to create a multiplexed neurochip (working with Huan and Wei-Ssu). In her off time, she likes to compete in triathlons.

William is a junior transfer from College of the Canyons where he received his B.S. degree. At UCLA, he is majoring in Neuroscience. He hopes to eventually conduct his research in the field of neuroimmunology and virology in order to better understand disease mechanisms and help develop new treatments.

Brandon Yoshida

Brandon Yoshida

Brandon is a second year undergraduate persuading a degree in Chemistry. His interests are slighted towards the organic side of the science, and he hopes he can apply the knowledge he's learned in the classroom to the lab. He is eager to study the deeper intricacies of the serotonin transmitter study and cannot wait to contribute to the scientific world.
