Biography
Geerling studied medicine at the medical school of the RWTH Aachen University and in England. In 1994 he successfully completed his MD thesis - tutored by M. Reim - on Examinations on cornea and conjunctiva after alkali burns by means of scanning electron microscopy and energy-dispersive of x-ray analysis. He obtained board certification as an ophthalmologist in 1996 and worked until 2005 at the department of Ophthalmology of the University Hospital of Schleswig-Holstein in Lübeck. During this period he also was associated as an honorary scientist to the Institute of Biomedical Optics (former Medical Laser Center) of the University of Lübeck.

From 1997 until 2000 (funded by the DFG and Special Trustees) and in 2003 he worked at Moorfields Eye Hospital and the associated Institute of Ophthalmology, University College London receiving subspecialist training from John KG Dart, J Richard O Collin and Geoffrey E Rose in corneal and oculoplastic surgery. He also worked in the basic science laboratory of Sir Peng T Khaw on corneal wound healing.

From 2000 on, Geerling worked as corneal consultant in Lübeck introducing corneal lamellar surgery. In 2003 he completed his Habilitation and was promoted to a lecturer at the University of Lübeck with a thesis on Natural Tear Substitutes. In 2005 he was called to serve an assistant professor for Ophthalmology at the University of Würzburg and became Deputy Director of the Department of Ophthalmology. In Würzburg he received subspecialist training in glaucoma surgery and expanded the local Lions eye bank. In 2011 he moved as Professor for Ophthalmology and Director of the Universitäts-Augenklinik Düsseldorf to the University of Düsseldorf.

Geerling is among others member of the "Deutsche Ophthalmologische Gesellschaft". He has received several national and international awards. Since 2005 he is editor of Current Eye Research.

Research
Geerling's clinical and scientific interests and activities are focused on natural tear substitutes, tissue constructs for ocular surface reconstruction and regeneration as well as new transplantation techniques for the treatment of corneal and ocular surface disorders, in particular dry eye, Corneal diasease and keratectasias. He was one of the first to introduce modern lamellar corneal graft techniques in Germany and intraoperative optical coherence tomography in Ophthalmology.

His surgical specialty lies in the anterior segment of the eye, with a particular focus on corneal transplantation. In addition he is specialised in glaucoma and oculoplastic surgery, including lacrimal and orbital tumor surgery. He has published more than 150 manuscripts in scientific journals and books and has edited two books.
