DESCRIPTION:Sexual reproduction is a critical biological process\, where tw
 o organisms physically fuse their gametes to produce a new\, genetically u
 nique individual. The mechanical constrains for two cells to meet pose obv
 ious physical limitations\, which are even more apparent in land plants\, 
 which often accomplish sexual reproduction even when miles apart. These li
 mitations are even more apparent in those plants that use wind as the prim
 ary means for dispersal\, a mechanism present even in flowering plants whe
 re animal dispersal is otherwise very common. Morphological studies have h
 ighlighted that whilst pollen from wind pollinated species is smoother tha
 n animal dispersed one\, wind dispersed spore during early land plant hist
 ory show complex\, ornamented surfaces. This observation remains paradoxic
 al mainly due to the lack of sophisticated computational frameworks to stu
 dy and understand pollen aerodynamics. We developed one such framework to 
 study how ornaments impact aerodynamic properties in the range where flow 
 changes from laminar to turbulent regimes. Our preliminary results seem to
  have solved this paradox\, emphasising that the beneficial effect of orna
 ments is proportional to particle size. \n\nDr. Marco D'Ario was born in R
 ome\, Italy\, but moved to England when he was 23. He lived in England for
  more than ten years\, where he did his college studies and graduated in B
 iotechnology at the University of Manchester. He did his Ph.D. at the John
  Innes Centre in cell and developmental biology\, where his team discovere
 d the mechanism for cell size regulation in the plant meristem. After my P
 h.D.\, fascinated by paleobotany\, he obtained the Gatsby Grant for Except
 ional Researcher to develop software for the three-dimensional reconstruct
 ion and biomechanical analysis of fossilized sporangia tissue. He is now a
 t Stanford as an HFSP fellow\, hoping to merge my interest in cell size\, 
 paleobotany\, and physics to understand the mechanisms of plant evolution.
