Research

Our group’s primary research focus is on understanding biological design. This includes nature’s mechanism for mechanotransduction. In this regard, we are interested in how extracellular matrix and cytoskeletal architecture potentiate and modulate the activation of mechanochemical and mechanoelectrical signaling pathways and genetic programs in cardiac, neural, and vascular smooth muscle cells and tissues. In order to study these mechanisms at different spatial scales, we use cellular and tissue engineering techniques that allow us to build custom-designed tissue constructs as experimental preparations.

Our group also has a growing effort in biologically-inspired design. This includes our work with electroactive polymer actuators, bio-inspired photonic systems, nanotextiles, and cell and tissue self-assembly as a system for rapid-prototyping of nonbiological systems.

Current areas of active research include:

Mechanotransduction – the role of mechanical stress, cell shape, and cell architecture on cell function.

Tissue Engineering – development of tissue grafts and scaffolds with unique structures and functions.

Brain Injury – investigating the mechanisms of traumatic brain injury at a cell and tissue scale.

Nanotextiles – developing new techniques for mimicking ECM networks for regenerative medicine and other industrial applications.

Microdevices – designing and building microscale soft biological constructs which retain their unique biological functionalities.

Welcome Dr. Ardoña! August 15th, 2017

The DBG would like to extend a warm welcome to our newest postdoctoral fellow, Dr. Herdeline Ardoña. Herdeline recently completed her Ph.D. in Chemistry at Johns Hopkins University,  where she was a part of Prof. Tovar’s lab.  Welcome, Herdeline!

Welcome Dr. Liu! June 23rd, 2017

The DBG would like to extend a warm welcome to our newest postdoctoral fellow, Dr. Qihan Liu. Qihan completed his Ph.D. in Prof. Zhigang Suo’s lab here at Harvard University, where he focused on the mechanics and physics of soft materials.  Welcome, Qihan!

Farewell Jack! June 16th, 2017

The DBG would like to wish Jack Zhou all the best as he leaves us for his next adventure – Medical School. Congratulations Jack!

The DBG welcomes the Orientation and Reach-Back Training class of the U.S. Army May 22nd, 2017

The DBG had the pleasure of hosting the Orientation and Reach-Back Training (ORBT) training class of the U.S. Army Research, Development and Engineering Command (RDECOM) Field Assistance in Science and Technology (FAST) program on May 17, 2017. ORBT is a multi-week mission overview program for senior-level Army officers, non-commissioned officers and Department of the Army civilians on the mechanisms for identifying and resolving technology capability gaps for units in their area of operation. The class visit to Professor (Lieutenant Colonel, Reserves) Parker’s Lab is their only visit to a Lab outside the Department of Defense.

The class met with DBG veterans and attended presentations on Stronger, Tougher, and Lighter Soldier Protection Systems; Nanofiber Scaffolds for Wound Healing/Dressings; Traumatic Brain Injury – Understanding Disease Mechanisms; Fibrous Scaffolds for Tissue Engineered Foods; Cells as Engineering Materials – the Cyborg Ray Project; Cuttlefish Inspired Camouflage; and our unique program for embedding Artists-In- Residence in the Lab.

Guests included members from the U.S. Army Research, Development, and Engineering Command (RDECOM); U.S. Army Engineer Research and Development Center (ERDC); U.S. Army Corps of Engineers; Army Research Laboratory; and RDECOM Research, Development and Engineering Centers.

Pictured below are (clockwise from bottom left): DBG Artist-in- Residence Karaghen Hudson (Harvard Class of 2018); Ms. Valerie Carney (ERDC); Dr. Aimee Poda (ERDC); Dr. (Colonel, Reserves) Steve Hart (RDECOM); Veteran and Program Coordinator John Laursen (Army Retired); Dr. Jerry Ballard (ERDC); Mr. Nathan Frantz (US Army Corps of Engineers); Visiting Scholar and Brigadier General Michael D. Phillips (USA Retired); Dr. Samantha Chambers RDECOM Science Advisor to the XVIII Airborne Corps; and Lieutenant Colonel Jovanna Nelson.
