SUMMARY:Raluca Eftimie: Mathematical mechanisms behind pattern formation in
  biological aggregations
DESCRIPTION:ABSTRACT: \nPattern formation is one of  the most studied aspe
 cts of animal communities. Some of the most  striking patterns observed in
  these communities are related to the  behaviour displayed by animal group
 s: from migrating herds  of ungulates\, to zigzagging flocks of birds\, or
  the rippling waves of  Myxobacteria.  Understanding the biological  and 
 mathematical mechanisms behind the formation of these patterns\, as  well 
 as the abrupt transitions between these patterns\, has become an  active a
 rea of research. In this talk\, I will present  and investigate a class of
  nonlocal hyperbolic models introduced to  describe the formation and move
 ment of self-organized biological  aggregations. After a brief discussion 
 of the models\,  I will focus on the large variety of spatial and spatiote
 mporal  patterns displayed by these models\, and discuss the mathematical 
  approaches taken to investigate them. I will conclude by presenting some
  open problems related to the mathematical mechanisms  behind some of the 
 more complex patterns.\n\n\nADDITIONAL INFORMATION:\n\n\nMy research cover
 s two main areas: (a) biological aggregations\,  with a focus on the forma
 tion\, structure\, and movement of these  aggregations\; (b) cancer immuno
 therapies.  \n\nDuring my PhD at University of Alberta\, I proposed a gen
 eral  modelling framework to understand the multitude of aggregation patte
 rns  observed in biological aggregations. For this work\, in 2009 I was  a
 warded (by the Canadian Applied and Industry Mathematics  Society (CAIMS))
  the “Cecil Graham Doctoral Dissertation Award”. \n\nAs a postdoctora
 l fellow at McMaster University\, I collaborated  with both immunologists 
 and mathematicians to model and identify the  biological mechanisms behind
  the interactions among immune cells\, cancer  cells and viruses\, with th
 e purpose of improving  existent cancer immunotherapies. In November 2011\
 , I was awarded a  “MITACS Postdoctoral Research Projects – Strategic 
 Project Award” to  mathematically identify and investigate cancer biomar
 kers that could be  used to improve the effectiveness of oncolytic therapi
 es  for skin cancer.
