Kadri Toome and Tambet Teesalu of the laboratory of Cancer Biology participated in the joint symposium of the Finnish Synthetic Chemistry Society, the Medicinal Chemistry Committee of the Finnish Pharmaceutical Society and the Finnish Peptide Society “Emerging targets and molecules in middle space” (Helsinki, Finland, August 24-27, 2015). Kadri’s poster “Development and in vivo validation of blood-brain barrier targeting peptides” (authors: Toome K, Säälik P, Willmore AM, Tarmo Mölder T, Sudakov A, Kõiv K, Nikonov A, Teesalu T) was awarded the best poster prize. Tambet presented an invited talk entitled „Tumor homing peptides v2.0: streamlined discovery and applications for targeted payload delivery”.
At the beginning of March a new member Maarja Haugas joined with the Lab of Cancer Biology. After ten years in Finland at the University of Helsinki, where she defended a PhD degree in developmental biology and veterinary anatomy in 2011 and continued as a postdoctoral researcher in developmental neurobiology, she has returned to beloved University of Tartu. She has background in molecular and developmental biology and in neuroscience, as well as know-how in histology.
Starting from 1st of February a new lab member has joined us. Pablo David Scodeller is from Argentina and he concluded his PhD studies in the University of Buenos Aires under the supervision of Dr. Ernesto Calvo. He then went on to work in the 'Chemistry of Nanomaterials' group led by Dr. Galo Soler Illia of Buenos Aires, under CONICET fellowship. For the last two years he's been working in the 'Vascular Mapping Laboratory' of Dr. Erkki Ruoslahti at Sanford-Burnham Medical research Institute, in La Jolla, USA. His main research interests are: Nanomedicine, Tumor microenvironment, drug penetration, drug delivery, adjuvants of oncolytic drugs. Phage display in vivo and in vitro. Neurodegenerative diseases and brain injuries. His main hobbies include: cogitations over beer, tango music, attending milongas, and the study of the Buenos Aires jargon called Lunfardo .
On 17th of September Kairit Šor joined Cancer Biology group as a executive administrative assistant. Her duties are taking care of grant financials (budgets, expenses etc) and overall office problems. Please do not hesitate to contact her with mentioned issues.
About her: she has more than 5 years of experience working in University of Tartu also as a project manager, has a BA in classical philology and soon to be graduate her master studies of philosophy of science.
Prof. Tambet Teesalu presented his work on discovery and application of tumor homing peptides for targeted delivery of drugs and nanoparticles on the EMBO Young Investigator Program Cancer Group meeting in Marseille, France.
