 Weimer Lab - 2015

 

 
Jill Weimer, PhD
Jill is an Associate Scientist in the Children’s Health Research Center and Assistant Professor in the Department of Pediatrics at the Sanford School of Medicine, USD. Before joining the Children’s Health Research team at Sanford, Dr. Weimer completed a BS and PhD in Neuroscience at the University of Rochester and a postdoctoral fellowship at the University of North Carolina, Chapel Hill in the Neuroscience Center.
 
Sanford Research Seung-Yon Koh, PhD   
Seung-Yon Koh, PhD
Seung-Yon completed a Masters in Animal Science at Dan Kook University in Chonan, Korea before coming to South Dakota to pursue her PhD.  Her doctoral work at SDSU in the laboratory of Dr. David Francis focused on the characterization of the receptor binding domain of enterotoxigenic Escherichia coli K88ad.  Her focus in the Weimer lab is to understand the impact that various guanine exchange factors have on regulating the proliferation of intermediate progenitors (ie., basal/multipolar progenitors) in the developing cerebral cortex. 
 
  Jacob Cain, PhD
Jacob graduated from the University of North Dakota in 2014 with his PhD. His doctoral work at UND looked at the role of Vascular Endothelial Growth Factor A isoforms in neural and vascular development. His focus in the Weimer lab is to understand the impact that various guanine exchange factors have on regulating the proliferation of intermediate progenitors (ie., basal/multipolar progenitors) in the developing cerebral cortex.
 
    Derek Timm 
Derek earned his Bachelor’s Degree in chemistry from South Dakota State University. As an undergraduate, he worked in the residue analysis laboratory under the supervision of Dr. Duane Mathees, testing plant and animal samples for pesticides. After graduating in 2008, Derek joined Dr. Qiangrong Liang whose lab focuses on cardiovascular disease. Derek provided support for studies on resveratrol, diabetic cardiomyopathy, and caloric restriction as well as an independent study focused on Doxorubicin induced cardiotoxicity. He transitioned to the Weimer lab in 2013, where his research focuses on identification of novel autoantibodies associated with Batten disease and characterization of novel mouse models of this family of disease.
    Ryan Geraets
Ryan graduated from South Dakota State University (‘09) with a Bachelor’s degree in biology and microbiology.  He then joined the Pearce lab as a Research Associate (‘10-‘11) where he focused on NCL biomarker discovery.  In August 2011, he entered the MD/PhD program at the University of South Dakota Sanford School of Medicine.   He is currently working on his PhD within Dr. Pearce’s laboratory.  His projects focus on discovering pharmacotherapeutic options for various forms of Neuronal Ceroid Lipofuscinoses (NCL).  Due to the nature of Ryan’s projects, he also works closely with Dr. Weimer’s laboratory.
    Katherine White
Katherine graduated from the University of Missouri in 2014 with a BS in Animal Sciences. During her undergraduate career she worked on a project intended to improve porcine in vitro embryo production. As a Research Associate in the Weimer lab she works on a variety of projects, including assisting in the characterization of swine models of neurofibromatosis type 1.
    Rachel Laufmann
Rachel Laufmann is an undergrad from the University of South Dakota working on a Bachelors in Molecular Biology and a minor in Chemistry. She is a former REU student and has worked on evaluating the effectiveness of LKE treatment on Neuronal Ceroid Lipofuscinosis (NCL) mouse models. Currently she is working on her senior thesis; comparing the broad pathology of mutant and wild type mice to determine if there are notable differences outside of the CNS that could lead to future combinatorial treatments
    Rebecca Vandebraak
Rebecca is a high school student at Washington High School and is planning on studying biochemistry. She joined the Weimer team as a PROMISE scholar in the summer 2014. Rebecca continues to help in the lab by identifying the role of Cln6 in developing neurons during neurogenesis
    Samantha Davis
Sammy graduated from University of Northwestern - St. Paul in 2014 with a B.S. in Biology. During her undergrad she worked with stream macroinvertebrates and their pollution tolerances to determine stream water quality. As a Research Associate in the Weimer lab she does mouse behaviors on both the CLN6 and CLN3 projects. She also helps with maintenance of the animal colony including genotyping of transgenic mice.
    Jon Brudvig
Jon is working on his PhD in Neuroscience through the Basic Biomedical Sciences program at The University of South Dakota. After completing his Bachelor of Science in Biology at USD, he joined the Weimer Lab to study the molecular mechanisms of cortical development. Jon uses a variety of molecular approaches including transgenic mice, in utero electroporation, and BioID to study how myristoylated alanine-rich C kinase substrate (MARCKS) influences polarity and signaling in developing neurons.
    David Sturdavent
David graduated from Augustana University with a Bachelor’s degree in chemistry. During his junior and senior years, he was a protein research intern at POET, exploring and implementing methods to recover and purify proteins from POET’s co-products including analysis of the proteins functional properties. After graduating in worked for South Dakota Innovation Partners as a research associate, collaborating with both Cyanosun Energy and Prairie AquaTech. His focus in the Weimer lab is small molecule drug screening on patient fibroblasts who are affected by Batten’s disease.
    Daniel Kota, PhD
Daniel is a Staff Scientist in the Regenerative Medicine Program directed by Dr. Weimer. Before joining Sanford Research, he earned his BS and MS in Biology in Brazil, PhD in Biomedical Sciences at Texas A&M University and completed his post-doctoral training at The University of Texas. His research focuses in developing cellular therapies utilizing adult-derived stem cells.
    Jordan Dykstra
Jordan graduated from South Dakota State University in 2014 with a Bachelor’s Degree in Biology and a minor in Chemistry. During his undergraduate years, he was also a member of the SDSU Men’s Basketball program. After a short stint playing for a European professional basketball club, he joined the Regenerative Medicine project in August 2015. Among other projects, he has been heavily focused on characterizing the stromal vascular fraction of adult-derived adipose tissue and how this autologous fraction can be used in the recovery of patients following clinical procedures. He has strong interest in the unique characteristics of stem cells and what their future use will be in the medical field. Jordan will be starting medical school at the University of South Dakota-Sanford School of Medicine in July 2017.
