Mattias Kretzler, M.D., Warner-Lambert/Parke-Davis ProfessorMedicine/Nephrology and Computational Medicine and Bioinformatics/University of Michigan
Bio: I am a nephrologist and translational physician scientists leading a multidisciplinary research team at the Michigan Kidney Translational Medicine Center. My overarching goal is to implement precision medicine for kidney diseases starting with defining diseases based on their molecular mechanisms and then using this knowledge to develop targeted, therapeutic interventions. To achieve this goal, I have developed a research pipeline that is based on integrated systems biology analysis of prospective, international, kidney biopsy cohorts which I have led over the last 24 years.
My research team integrates large scale data across the genotype-phenotype continuum of chronic kidney diseases to carefully curate environmental exposures, genetic predispositions, epigenetic markers, transcriptional networks, proteomic profiles, metabolic fingerprints, digital histology, and prospective clinical disease characterization. Based on the multi-scalar data sets we have generated across the multiple cohorts we have initiated and sustained, we are now acquiring new insights from the population down to the individual patient level to define molecular processes at the single cell level in kidney development, health, and disease.

Kevin Chen, M.D., Frances and Kenneth Eisenberg Emerging Scholar, Clinical Assistant Professor of Neurosurgery, Clinical Assistant Professor of Neurology, University of Michigan
Bio: Dr. Chen is the Frances and Kenneth Eisenberg Emerging Scholar in the University of Michigan Neuronetwork for Emerging Therapies, and Clinical Assistant Professor in Neurosurgery with joint appointment in Neurology. He is a clinically practicing neurosurgeon with sub-specialty training in stereotactic/functional neurosurgery, using techniques to modulate and correct abnormal neural circuits (Parkinson’s disease, essential tremor, chronic pain, epilepsy, etc.). Stem cells are a particular focus of Dr. Chen’s research, specifically induced pluripotent stem cells (iPS), and how iPS cells might model and/or treat neurodegenerative diseases like Alzheimer’s disease and amyotrophic lateral sclerosis. His particular interest is in inhibitory interneurons, how interneurons malfunction in disease, and how inhibitory regulation can be restored. He is applying single cell and spatial approaches to isolate specific interneuron subtypes within their neuroanatomic context for deeper understanding of disease pathophysiology. The eventual ability to modulate neural activity using stem cells may also be applied to other conditions, such as epilepsy, stroke, chronic pain, and psychiatric diseases.

April Kriebel, Ph.D., Postdoctoral Fellow, University of Michigan
Bio: April Kriebel defended her doctoral dissertation in the Department of Computational Medicine and Bioinformatics March 11, 2024. She joined Dr. Joshua Welch’s laboratory in 2020, and her dissertation work was focused on developing computational methods for integrating molecular and anatomical data with spatial transcriptomics. She is an alumna of the Genome Science Training Program and an F-31 recipient.
Her first project as a graduate student focused on the development of UINMF, a single-cell dataset integration algorithm that could integrate datasets using both shared and unshared features. This algorithm proved especially advantageous when integrating scRNA-seq datasets with spatial transcriptomic datasets that often measured fewer genes. Genes not captured during the spatial transcriptomic protocol but were measured in the scRNA-seq data could now be leveraged when integrating the two datasets, leading to the identification of more refined cell type distinctions within the spatial transcriptomics data.
Bio: Dr. Chapkin is an NIH/NCI R35-Outstanding Investigator Awardee and an American Association for the Advancement of Science (AAAS) Fellow.

Bio: Dr. Ying Ma is an Assistant Professor at the Department of Biostatistics and the Center for Computational Molecular Biology at Brown University. Her research interests focus on developing efficient statistical learning methods to address a variety of biological problems and computational challenges in genomics and genetics. These challenges typically arise with the high-dimensional data generated by rapidly evolving sequencing technologies, e.g., single-cell RNA-seq (scRNA-seq), and spatially resolved transcriptomics (SRT). With the emergence of these large-scale data, she has been continually motivated to develop tailored statistical models to advance our understanding in cellular heterogeneity, tissue organization, and the underlying mechanisms of various types of cancers. Besides her genomics research, she also works on genetic risk prediction and polygenic risk score problems in large biobanks such as UKBiobank, and MGI.
Antonio Morales-Hernández, Ph.D., University of Michigan
Bio: Antonio Morales-Hernández joined the laboratory of Drs. Pedro Fernández-Salguero and Jaime Merino, where he earned his PhD in Biochemistry, Molecular Biology, and Genetics at the University of Extremadura (Spain). His PhD project focused on the function of the dioxin receptor in cell differentiation and lung regeneration. While pursuing this work, he received excellent training in molecular biology, genetic mouse modeling, cell differentiation and trafficking and the relatively unexplored and exciting field of transposable elements (TEs). This work piqued his interest in Stem Cell Biology and so he decided to pursue further training in this area and therefore joined Dr. Shannon McKinney-Freeman’s laboratory at St. Jude Children’s Research Hospital for his postdoctoral training. Since then, he gained expertise in hematopoietic stem cell (HSCs), what has allowed him to develop his own research program focused on elucidating GPRASP gene expression refines HSCs functional heterogeneity along with side projects focused on general HSCs biology and B cell lymphomagenesis.

Xin Luo,Ph.D., Department: Computational Medicine and Bioinformatics
Bio: My current research direction is about cell-cell communication and single-cell analysis. I will work on single-cell multi-modality integration in the future. Spatial single-cell analysis interests me a lot as spatial-level cell-cell communication has a lot to explore.
Joshua Sodicoff, B.S.E. , Department: Computational Medicine and Bioinformatics
Bio: In my current role, I am developing a methodology for cell type deconvolution of heterogeneous tissue for application to large scale spatial transcriptomic data collected on the murine brain. Determination of the distributions of both well characterized and novel types identified with scRNA-seq data will allow for integration with physiological data and inference on the impact of present fine tissue structures. More generally, I am interested in the spatial organization of biological structure as a manifestation of the emergent properties of small-scale biochemical and genetic interactions with applications in microbial ecology and evolutionary biology.

Research Interests: We will use multimodal approaches; single-cell RNA-seq (scRNA-seq), mass cytometry (cytometry time-of-flight (CyTOF) immune phenotyping), and multiplex imaging to discover the spatial phenotypic signatures of the tumor microenvironment in brain tumors.
Yuji Mishina, Ph.D., William R. Mann Professor of Dentistry, School of Dentistry
Bio: Dr. Mishina’s laboratory is interested in functions of BMP signaling during bone development/remodeling and craniofacial development. Several specific projects include mechanisms of how osteoclasts regulate osteoblast functions in a spatiotemporal manner as a downstream event of BMP signaling, cell fate specification mechanisms in cranial neural crest cells towards chondrogenic lineage, impacts of nanofibrous biomaterials as stem cell niche, identification of crossover points between BMP signaling and mechanosensing for bone homeostasis, and investigation of cellular mechanisms of heterotopic bone formation to identify therapeutic options. We fully utilize genetically modified mouse lines in combination of cellular and molecular approaches including single-cell omics to uncover the above mentioned mechanisms.
