Cole A. DeForest, PhD (Chemical Engineering)
While the potential for biomaterial-based strategies to improve and extend the quality of human health through tissue regeneration and the treatment of disease continues to grow, the majority of current strategies rely on outdated technology initially developed and optimized for starkly different applications. Therefore, the DeForest Group seeks to integrate the governing principles of rational design with fundamental concepts from material science, synthetic chemistry, and stem cell biology to conceptualize, create, and exploit next-generation materials to address a variety of health-related problems. We are currently interested in the development of new classes of user-programmable hydrogels whose biochemical and biophysical properties can be tuned in time and space over a variety of scales. Our work relies heavily on the utilization of cytocompatible bioorthogonal chemistries, several of which can be initiated with light and thereby confined to specific sub-volumes of a sample. By recapitulating the dynamic nature of the native tissue through 4D control of the material properties, these synthetic environments are utilized to probe and better understand basic cell function as well as to engineer complex heterogeneous tissue.

Cecilia Giachelli (Bioengineering)
My lab is interested in applying stem cell and regenerative medicine strategies to the areas of ectopic calcification, tissue engineering, biomaterials development and biocompatibility.

Deok-Ho Kim (Bioengineering)
Through the use of multiscale fabrication and integration tools, Dr. Kim's research focuses on the development and applications of biomimetic cell culture models and functional tissue engineering constructs for high-throughput drug screening, stem cell-based therapies, disease diagnostics, and medical device development.

Daniel G. Miller (Pediatrics)
Dr. Miller and members of his research group utilize induced pluripotent stem cells (IPSc) made from the skin cells of individuals with Facioscapulohumeral Muscular Dystrophy (FSHD) to understand the etiology of this debilitating condition. The hypothesis is that FSHD is caused by a defect in muscle development and/or maintenance so studying differences between control and patient embryonic cells as they differentiate to form muscle may reveal key mechanisms of disease pathology. Dr. Miller is also interested in treatment strategies for genetic conditions so members of his research group use vectors based on Adeno-Associated Virus (AAV) to perform gene targeting in primary human cells. This approach is currently being applied to keratinocytes from patients affected with a skin blistering condition called Epidermolysis Bullosa. The molecular consequence of disease-causing mutations can also be studied by creating the same mutations in primary human cells, or correcting mutations in cells from affected patients.
Dr. Miller also sees patients with genetic conditions in the pediatric medical genetics clinic at Children’s Hospital.

Ray Monnat, PhD (Pathology and Genome Sciences)
Our research focuses on human RecQ helicase deficiency syndromes such as Werner syndrome; high resolution analyses of DNA replication dynamics; and the engineering of homing endonucleases for targeted gene modification or repair in human and other animal cells.

Buddy Ratner (Bioengineering)
Stem cells proliferate and differentiate in response to micromechanical cues, surface biological signals, orientational directives and chemical gradients. To control stem cell proliferation and differentiation, the Ratner lab brings 30 years experience in surface control of biology, polymer scaffold fabrication and controlled release of bioactive agents to address the challenges of directing stem cell differentiation and subsequent tissue formation.

Michael Regnier (Bioengineering)
The Regnier lab works in a highly collaborative environment to develop both cell replacement and gene therapies approaches to treat diseased and failing hearts and skeletal muscle. Cell replacement strategies include development and testing of tissue engineered constructs. Gene therapies are target and improve myofilament contractile protein function.

Mehmet Sarikaya (Genetically Engineered Materials Science and Engineering Center, Materials Science and Engineering)
Our research focuses on Molecular Biomimetics in which we use combinatorial mutagenesis to select peptides with specific affinity to desired materials, use bioinformatics-based pathways to in-silico design peptides, tailor their structure and function using genetic engineering protocols, couple them with synthetic self-assembled molecular hybrids, and use them as molecular tools in practical medicine and materials technologies. Our focus at the biology/materials interface incorporates molecular biology and nanotechnology, computational biology and bioinformatics, molecular assemblers, bio-enabled nanophotonics (quantum-dot and surface-enhanced probes), and peptide-based matrices for neural, dental and soft tissue regeneration.

Thomas N. Wight, PhD (Benaroya Research Institute)
This investigator leads a research program focused on the role that the extracellular matrix molecules, proteoglycans and hyaluronan, play in regulating vascular cell type and the regulation of extracellular matrix assembly. These pathways are fundamental to understanding the growth of new blood vessels in different tissues of the body, and have potential for direct tissue regeneration applications through the use of proteoglycan genes to bioengineer vascular tissue.

Ying Zheng, PhD (Bioengineering)
Dr. Zheng's research focuses on understanding and engineering the fundamental structure and functions in living tissue and organ systems from nanometer, micrometer to centimeter scale.
