As a PhD student at Harvard Medical School who is co-advised by Professor Lewis, my work focuses on gene-regulation and cell-lineage decision making in the early mammalian embryo. In collaboration with the Lewis group, I am interested in how maternal in vivo conditions can be recapitulated in vitro.

I am working on programming 3D shape change in actuators by controlling molecular orientation at the filamentary scale while programming structure at the macroscopic scale via direct ink writing. I am especially interested in developing 3D liquid crystal elastomer actuators for use in soft robotics.
As part of the bioprinting team, I am investigating printing of hierarchical blood vessel systems with complex cellular interactions. Scaling up the bioprinting approach to incorporate biologically relevant geometries and cellular variety could be the next step towards building functional tissues mimicking complexity and organization of tissue physiology.
My research aims to create materials and structures with novel and outstanding (mechanical) properties. To achieve these properties, I develop new fabrication techniques based on the direct-ink writing process and combine them with computational methods to fully exploit the design space.
During her PhD, Radhika worked on developing fiber-optic probes for minimally invasive surgical applications. This included development of microscale optical-ultrasound generating devices and interferometric pressure sensors for cardiovascular microsurgery, using micro/nano-fabrication techniques to form and integrate polymeric 3D structures to the endface of glass optical fibers. At the Lewis Lab, Radhika is working on ultrasound-based acoustophoretic printing mechanisms and associated applications.
During his Ph.D., Daniel developed 3D in vitro tumor models to study how the tumor microenvironment’s physical properties contribute to cancer progression. At the Lewis Research Group, Daniel’s research focuses on using 3D bioprinting to manufacture vascularized biological tissues for applications in both regenerative medicine and disease modeling.

Benito received his PhD degree in 2015 after carrying out studies in SiC ceramics and graphene-ceramic composites in the Institute of Ceramics and Glass (ICV-CSIC) in Madrid. The aim was the enhancement of the physical properties of these ceramic-based materials, fabricated both as bulk and as 3D-printed scaffold structures. In the Lewis group, Benito’s research is centered on the development of novel, 3D-printed ceramics with different functionalities.
During his PhD, Mark developed a method for rapid 2-D and 3-D laser printing of biomaterials using two photon microscopy. He applied his printer to develop detailed vascular structures, and to direct neural development. At the Lewis Research Group, Mark is developing large-scale vascular networks for tissue and organ printing using direct-ink writing methodologies. He is also interested in combining different 3-D printing methodologies to achieve novel capabilities in the field of additive manufacturing of biological materials.
Sebastien received his PhD from the department of Mechanical Engineering at MIT under the supervision of Pr. Roger Kamm. There, he developed microfluidic devices to expose cells to complex and dynamic concentration profiles within a 3D extracellular matrix. In addition, by combining optogenetic technology and microfluidics, Sebastien designed a platform that allowed compartmentalized 3D coculture of lightexcitable motor neurons and muscle cells. In the Lewis Lab, Sebastien's research focuses on utilizing 3D bioprinting to engineer vascularized and functional biological tissues. He is also interested in the development of tools and strategies to enhance the scale and versatility of 3D printing.

The setup and fine tuning of all the different parameters in additive manufacturing often takes much longer than the actual print itself. I am interested in the development of novel additive manufacturing systems with process feedback to decrease setup time, increase printing throughput and optimize print quality.
