Dr. Koenig’s main area of research is in tissue regeneration and healing, with emphasis on wound and tendon healing in horses. Investigation of different modalities for tissue regeneration and wound healing, such as allogeneic cord blood stem cells, low level light lasers and shock wave treatment. These modalities accelerate the healing process through interacting with different cellular pathways. Research has been done to investigate the effect of low level light lasers and shock waves on wound healing in horses. Also, the antiinflammatory properties of allogeneic cord blood stem cells on induced synovitis in horses has been demonstrated. The effect of repeated administration of stem cells in the treatment of superficial digital flexor tendinitis is currently evaluated. Another current area of research is the effect of shockwave application on stem cells.

My main role in our research team is as a clinician and surgeon. As clinician I usually design and participate in the in vivo trials, either using animal models or clinical cases. I do not have my on lab, but collaborate with Dr Koch and our graduate students are trained in his lab.
