Current Lab Members

Margaret A. Titus

Principle Investigator (P.I.)
Department of Genetics, Cell Biology, and Development

Margaret (Meg) Titus received an AB in Biochemistry with honors from Smith College where she began her research career working on a plant myosin. She then studied myosin-linked regulation in invertebrate muscles at Brandeis University and earned her PhD under thesis advisor Dr. Andrew G. Szent-Györgyi. She then initiated studies of non-muscle myosins using molecular genetic approaches as a postdoctoral fellow in Dr. Jim Spudich's lab at Stanford. M.A. Titus has since continued to investigate the role of diverse myosin family members in cell migration, chemotaxis, adhesion and endocytosis in the social amoeba Dictyostelium.


Taylor Harding

Postdoctoral Fellow

Taylor earned his doctorate in Molecular, Cellular, Developmental Biology and Genetics from the University of Minnesota in Summer 2018. He is currently implementing genome engineering strategies in Dictyostelium and is performing pan-cancer informatic analyses to determine the scope of MyTH4-FERM myosins' impact on human cancers.


Ashley Arthur

Graduate Student
Molecular, Cellular, Developmental Biology and Genetics

Ashley obtained a BS in Genetics from the University of WI. After completing her BS she worked as a lab technician at the University of WI studying neuronal polarity and also at the University of Chicago studying thymic B cells. For her PhD thesis, Ashley is interested in how filopodia initiate from the cell cortex, and how MyTH4FERM myosin in concert with VASP and other actin-binding proteins facilitate filopodia initiation. She is building a stochastic model of filopodia initiation and is working on her concurrent M.S degree in Bioinformatics and Computational Biology. Ashley is passionate about gender equality in STEM and started the Girls Who Code @ UMN Club at the University of MN.


casey_profilewwCasey Eddington

Graduate Student
Biochemistry, Molecular Biology, and Biophysics

Casey received a B.S. in organismic biology at Northeastern State University (NSU) in Oklahoma. After completing this, he pursued his M.S. under Dr. Sapna Das-Bradoo at NSU, where he investigated protein-protein interactions involved in DNA replication and genome stability. Currently, Casey is interested in finding potential binding partners of Talin and DdMyo7, two proteins that play a role in cellular adhesion.



 Annika SchroderwwAnnika Schroder - Lab Technician

Annika graduated with her B.A. in Biology and Scandinavian Studies from the Gustavus in June 2019.  She is studying filopodia formation amoeboid chemotaxis as a postbaccalaureate. 



hibo_profilewwHibo Wehelie

CBS Undergraduate Student

Hibo is an undergraduate student in College of Biological Sciences, majoring in biochemistry. Her project is to assess the role of Myosin VII on the organization of intestinal microvilli in the nematode, C. elegans.
