Research Fellows
Leah Borden, Alana Fellow
Dr. Borden began her postdoctoral research in the Boyer lab in January of 2023. She is investigating how the matrix around heart cells is impacted during heart development in Down syndrome. In this work, Borden is developing new models to determine how an extra chromosome affects cell-to-cell communication during heart development. Dr. Borden earned her PhD in biomolecular engineering at the University of Maryland College Park, where she studied the properties and mechanics of soft material-tissue interfaces. Dr. Borden completed her undergraduate studies in Chemical Engineering at the University of Illinois at Chicago.
Dong Shin Park, Alana Fellow
Dr. Park joined the Tsai lab as a postdoctoral researcher in 2021. He is the studying the effects of prenatal, 40 Hz light and sound (Gamma ENtrainment Using Sensory stimuli, or GENUS) on brain development, gene expression and behavior in mouse models of Down syndrome. Park completed his PhD at the National University of Singapore, where he worked on human iPSC-derived brain organoids and macrophages, and studied neuro-immune interactions.
Bo Zhao, Alana Fellow
Dr. Zhao is a postdoctoral researcher in the Kellis lab, studying the effects of gene dosage on global gene expression in trisomy 21 brain cells. His approach is to systemically perturb genes and measure changes in expression in other genes in several cell types from the brain, to help identify the cause of the gene expression changes observed in DS. The goal is to identify key misregulated genes that disrupt key brain functions. Dr. Zhao joined the Kellis lab following a research position in the Department of Chemical Biology at Harvard, working on single-cell sequencing technology, and received his PhD from the University of North Carolina Department of Chemistry.
Alana Fellow Alumni
Cristina Blanco Duque
Dr. Blanco was a postdoctoral researcher in the Tsai lab who studied the interactions of Down syndrome, Alzheimer’s disease, and sleep. The Tsai lab had previously shown that sensory stimulation at a certain frequency may help reduce Alzheimer’s disease. Dr. Blanco studied the effects of this sensory stimulation on sleep in Down syndrome and neurotypical models, and investigated the potential interaction between beneficial activities during sleep and the protective effects against Alzheimer’s.
Michael Gutbrod
Dr. Gutbrod was a postdoctoral researcher in the Kellis lab, investigating the global gene expression changes in cells as a result of trisomy 21 and gene dosage changes. He is currently directing neuroscience investments at Santé Ventures, specializing in biotech company creation and early stage startup investments.
Ben Lengerich
Dr. Lengerich was a postdoctoral researcher in the Kellis lab, who employed machine learning models to study the cell-type specific changes in the Down syndrome brain in order to understand the contributions to the differences in levels of cognitive performance, from high-performing, low performing, and catatonic individuals. He is now an Assistant Professor of in the Department of Statistics at the University of Wisconsin.
Yixi Liu
Dr. Liu was a PhD student in the Boyden lab, where she developed a new form of expansion microscopy (ExM) to help construct a 3-D nanomap of proteins at synapses. With this methodology, the architecture of synapses in Down syndrome can be specifically analyzed. Liu is currently a postdoctoral fellow continuing her work in the Boyden lab.
Hiruy Meharena
Dr. Meharena was a postdoctoral researcher in the Tsai lab, and a Senior Alana Fellow. Working in the Tsai lab, Dr. Meharena developed patient-derived stem cell brain models to understand the consequences of Trisomy 21 on the nuclear architecture, function and how these alterations result in the phenotypic differences associated with the pathologies observed in Down syndrome. Meharena is now Assistant Professor of Neurobiology at University of California San Diego.
Tim Mullen
Dr. Mullen was a post-doctoral researcher in the Amon lab, studying the link between an imbalance in chromosome number and cancer. He is currently a research scientist at Be Biopharma.
Zeguan Wang
Mr. Wang was a PhD student the Boyden lab. His research aimed to develop novel microscopy techniques and to map the activity of neural circuits that are different in Down syndrome. Wang continues his work with the Boyden lab as a postdoctoral fellow.
Jiekun (Jackie) Yang
Dr. Yang was a post-doctoral researcher in the Kellis lab, where she analyzed gene expression patterns in Down syndrome and the impact of Alzheimer’s disease on these patterns. Yang is now an Assistant Professor in the Department of Genetics at Rutgers University – New Brunswick.
