Lisa Stehno-Bittel, PhD
President & Founder

Lisa Stehno-Bittel serves as president and founder of Likarda, LLC. Lisa began her career in health care as a physical therapist helping her patients rehabilitate from injuries or illness, but she was frustrated in the lack of progress for some of her patients.  She needed new tools to help them overcome life-changing diseases.  She went back to school to obtain a PhD from the University of Missouri in physiology and completed a pharmacology post-doctoral fellowship at the Mayo School of Medicine. With more than 25 years of research experience in the fields of cell biology and diabetes, she has over 70 publications in scientific journals. Lisa has received numerous awards, including Ingram Magazine’s “50 Kansans You Should Know” and the 2018 Kansas Entrepreneur of the Year Award.

Lisa enjoys water and snow skiing and traveling with her husband and kids. One of her favorite annual trips is heading to Sturgis each year on her motorcycle.

Francis Karanu, PhD
Senior Research Scientist

With a PhD in immunology and cell biology, Francis is a senior cell therapy researcher for Likarda, a world-class biotech research laboratory that works with science entrepreneurs, bio consortium members, and contract research organizations. Francis is part of a team that is developing a cell-based solution for dogs with diabetes, which will be an injectable islet transplant that will eliminate the need for daily insulin injections for diabetic dogs.

Francis began his career as a veterinarian, but quickly turned to his passion, biomedical research. Prior to joining Likarda, he was with Johnson & Johnson and worked extensively in a stem cell and regenerative medicine venture developing beta-like, insulin producing cells from pluripotent stem cells for the treatment of diabetes in humans, including isolation and characterization procedures. Francis’s methods for purifying cells derived from pluripotent stem cells were granted patent US20110212067. He has been author or co-author of many peer reviewed publications and patents.

Francis studied veterinary medicine at the University of Nairobi, Kenya, and completed his graduate training at Washington State University before beginning postdoctoral work at Robarts Research Institute / University of Western Ontario, London, Ontario where he worked on isolation and expansion strategies of human hematopoietic stem cells from cord blood and bone marrow.

Along with extensive experience in biotechnology/industry and academic research environments, Francis is very involved in diabetes care and management issues in underserved areas including Sub-Saharan Africa. He is active in Mariira Catholic Dispensary in Murang’a, Kenya where he volunteers his time and resources to provide medical supplies and equipment to support the organization’s mission. As an advisor on the Kenya Defeat Diabetes Association, he helps guide the grassroots group in tackling diabetes and high blood pressure through community education and support.

Lindsey Ott, PhD
Product Innovation Scientist

With a PhD in bioengineering and an eye for innovation, Lindsey is the director of product innovation for Likarda, a world-class biotech research laboratory that works with science entrepreneurs, bio consortium members, and contract research organizations.

Lindsey received her B.S. in biological/agricultural engineering from Kansas State University, her Ph.D. in bioengineering from the University of Kansas, and her postdoctoral training at the University of Kansas Medical Center. Her graduate research focused on biomaterials and tissue engineering, specifically developing biomaterial implants to treat tracheal stenosis in pediatric patients. Lindsey designed a synthetic nanofiber scaffold that could replace rib cartilage as an option to expand the trachea for infants and toddlers with a narrowed airway.

In her role at Likarda, Lindsey expands Likarda’s patented 3D cell cluster technology into other preclinical drug discovery applications like oncology, immunotherapies, and ADME-Tox. She has published work in the fields of tracheal tissue engineering, biomaterial fabrication, adult mesenchymal stem cells for musculoskeletal tissue engineering, and preclinical drug discovery using 3D hepatic organoids. Lindsey has presented at numerous conferences including the Biomedical Engineering Society, Society for Biomaterials, and the American Association of Pharmaceutical Scientists. She is also involved in K-12 science education programs by mentoring students and developing bioengineering-related curriculum for elementary school classrooms.

Stephen Harrington, PhD
Senior Research Scientist & Manufacturing Supervisor

Stephen wasn’t an analytical laboratory chemist for long before he discovered his passion for applied research. That passion drove him to graduate school, investigating novel biomaterials for improving islet transplantation, which also led to advancements in islet isolation and cryopreservation techniques. Promising results then led to his research collaboration with Likarda and the development of a novel micro-encapsulation process that was granted a US patent in 2017. This novel process for producing cell-hydrogel microspheres, termed core-shell spherification (CSS), has great potential in cell-based therapy as an injectable, immunoprotective, and customizable delivery system.

Conducting research and development for Likarda’s islet transplantation project gave Stephen a unique opportunity to observe directly the successful translation of Likarda’s patented micro-mold technology from an academic project to a revenue generating product, and strongly influenced his approach to research.

While his early research interest was in islet transplantation as a cure for type 1 diabetes, he became most interested in the use of biomaterials (specifically hydrogels) as immunoprotective and cell-supportive structures to improve and prolong islet transplants. Encapsulation within a hydrogel can prevent immune rejection without immunosuppression by physically blocking contact between host T- Cells and donor islet MHC molecules. Alongside transplantation studies, Stephen became involved in an additional project involving a novel single-cell based islet cryopreservation technique for the goal of improving donor tissue availability.

Stephen earned his undergraduate in chemistry from Emporia State University and holds a doctorate in bioengineering with a focus on biomaterials and tissue engineering from the University of Kansas. His dissertation gained recognition as a 2017 Argersinger Dissertation Award Nominee for Outstanding Doctoral Dissertation at the University of Kansas.
