Jonathan Wilker is an American scientist, engineer, and educator who focuses on developing marine animal-inspired underwater adhesives for use in surgery, construction, and other applications. His work has been profiled by The New York Times , [1] National Public Radio, [2] Popular Science, [3] and his research findings appear in many scientific journals, such as Nature, [4] Journal of the American Chemical Society, [5] [6] and ACS Applied Materials & Interfaces. [7] [8] He is a professor at Purdue University in West Lafayette, Indiana, where he teaches courses in inorganic chemistry and bioinorganic chemistry. Wilker has received a number of awards for his teaching including The College of Science Outstanding Teacher Award at Purdue University (2011). [9] In addition to being in the Department of Chemistry, he is also a Professor of Materials Engineering at Purdue University. Outside activities include advocacy for federal funding of science research and development. [10]
Wilker grew up in the Boston area. He has said that, when younger, visiting beaches with his parents and, when older, scuba diving have influenced the research pursued in his laboratory. As an undergraduate, Wilker studied chemistry at the University of Massachusetts, Amherst. He was a graduate student at the Massachusetts Institute of Technology in chemistry, working under Stephen Lippard. After graduation he spent time at the California Institute of Technology as a postdoctoral scholar in the laboratory of Harry Gray. In 1999 he moved to Purdue University to start his own research laboratory. [11]
Wilker's current research focus includes biomaterials, underwater adhesives, sustainability, polymer synthesis, biomimetic materials, marine biology, bioinorganic materials, sealants, coatings, hydrogels, and material characterization. His research group is working to understand how animals adhere to surfaces in the wet marine environment. [12] Much of this work has been with mussels and oysters. Key findings include observations indicating that mussels use iron to cure their protein-based adhesive. [13] Oysters have been shown to produce a cement with chemistry quite different from that of mussels. [14]
Another aspect of Wilker’s research program is in biomimicry. He is using information learned from marine biology to make new adhesive materials. Of note is development of a polymer adhesive that can bond more strongly than commercial Super Glue. Their laboratory has also made what may be the strongest known adhesive for bonding underwater. [15] [16]
Wilker is also working in applications development, in particular using biomimetic materials to develop new adhesives for general use as well as, specifically, for surgeries. [17] One challenge in replacing biomedical sutures and screws is obtaining adhesives that can set in the wet environment of the body.
Wilker has won numerous awards for his research including the PopTech Science Fellowship (2013), [18] the Alfred P. Sloan Foundation Research Fellowship (2002), [19] the Beckman Young Investigators Award (2001), [20] and the National Science Foundation Faculty Early Career Development (CAREER) Award (2001). [21] Wilker has spoken about his research at PopTech (2013) and TEDx Purdue (2018). [22]
In 2019, Wilker and his team launched the company Mussel Polymers Inc, where he acts as Lead Scientist. [23] Mussel Polymers is focused on developing adhesives in the form of poly(catechol-styrene) (PCS), which Wilker and his research team invented at Purdue University. [24]
In 2024, Wilker was noted as an important scientist in sustainability and climate change in the Grist 50 list. [25]
Biomimetics or biomimicry is the emulation of the models, systems, and elements of nature for the purpose of solving complex human problems. The terms "biomimetics" and "biomimicry" are derived from Ancient Greek: βίος (bios), life, and μίμησις (mīmēsis), imitation, from μιμεῖσθαι (mīmeisthai), to imitate, from μῖμος (mimos), actor. A closely related field is bionics.
Molecular engineering is an emerging field of study concerned with the design and testing of molecular properties, behavior and interactions in order to assemble better materials, systems, and processes for specific functions. This approach, in which observable properties of a macroscopic system are influenced by direct alteration of a molecular structure, falls into the broader category of “bottom-up” design.
A byssus is a bundle of filaments secreted by many species of bivalve mollusc that function to attach the mollusc to a solid surface. Species from several families of clams have a byssus, including pen shells (Pinnidae), true mussels (Mytilidae), and Dreissenidae.
Adhesion is the tendency of dissimilar particles or surfaces to cling to one another.
Plasma cleaning is the removal of impurities and contaminants from surfaces through the use of an energetic plasma or dielectric barrier discharge (DBD) plasma created from gaseous species. Gases such as argon and oxygen, as well as mixtures such as air and hydrogen/nitrogen are used. The plasma is created by using high frequency voltages to ionise the low pressure gas, although atmospheric pressure plasmas are now also common.
Bioadhesives are natural polymeric materials that act as adhesives. The term is sometimes used more loosely to describe a glue formed synthetically from biological monomers such as sugars, or to mean a synthetic material designed to adhere to biological tissue.
Layer-by-layer (LbL) deposition is a thin film fabrication technique. The films are formed by depositing alternating layers of oppositely charged materials with wash steps in between. This can be accomplished by using various techniques such as immersion, spin, spray, electromagnetism, or fluidics.
Reflectins are a family of intrinsically disordered proteins evolved by a certain number of cephalopods including Euprymna scolopes and Doryteuthis opalescens to produce iridescent camouflage and signaling. The recently identified protein family is enriched in aromatic and sulfur-containing amino acids, and is utilized by certain cephalopods to refract incident light in their environment. The reflectin protein is responsible for dynamic pigmentation and iridescence in organisms. This process is "dynamic" due to its reversible properties, allowing reflectin to change an organism's appearance in response to external factors such as needing to camouflage or send warning signals.
Phragmatopoma californica, commonly known as the sandcastle worm, the honeycomb worm or the honeycomb tube worm, is a reef-forming marine polychaete worm belonging to the family Sabellarididae. It is dark brown in color with a crown of lavender tentacles and has a length of up to about 7.5 centimeters (3.0 in). The worm inhabits the Californian coast, from Sonoma County to northern Baja California.
Nicholas A. Kotov is the Irving Langmuir Distinguished Professor of Chemical Sciences and Engineering at the University of Michigan in Ann Arbor, MI, USA. Prof. Nicholas Kotov demonstrated that the ability to self-organize into complex structures is the unifying property of all inorganic nanostructures. He has developed a family of bioinspired composite materials with a wide spectrum of properties that were previously unattainable in classical materials. These composite biomimetic materials are exemplified by his nacre-like ultrastrong yet transparent composites, enamel-like, stiff yet vibration-isolating composites, and cartilage-like membranes with both high strength and ion conductance.
The structure of carbon nanoscrolls is similar to that of a multi-walled carbon nanotube, but with a spiral-like rolled-up geometry and open edges at the ends.

Mussel foot proteins (MFP) are proteins secreted by mussels that enable them to securely anchor themselves to other mussels and other underwater structures. The proteins form sticky byssal holdfast fibers (BHF). Species from several families of clams have a byssus, including pen shells (Pinnidae), true mussels (Mytilidae), and Dreissenidae.
Diethylene glycol diglycidyl ether (DEGDGE) is an organic chemical in the glycidyl ether family with the formula C10H18O5.. The oxirane functionality makes it useful as a reactive diluent for epoxy resin viscosity reduction.
