Geodynamics Dynamics: Relationship between force and motion (Also force in equilibrium) Geodynamics: Dynamics of Earth (Mantle has a hegemony here) Why? Crust : Geology Core: Magneto-Hydrodynamics (MHD) Jyotirmoy Paul | Indian Institute of Science | JUGS GEOGLE 11 01-08-2020

Into the modeling world A scientific model is a physical and/or mathematical and/or conceptual representation of a system of ideas, events or processes. All models are beautiful! Jyotirmoy Paul | Indian Institute of Science | JUGS GEOGLE 12 01-08-2020

Why Geodynamicists model? • Time scale of natural process: Real time experiment is impossible • Number of variables/ unknown in natural system • Non-intuitive nature of physical properties • Non-linear nature of governing equations Jyotirmoy Paul | Indian Institute of Science | JUGS GEOGLE 13 01-08-2020

My Present Work Why cratons are still here? One of the grand challenges in Geodynamics (Olson et al. 2010) (Poupinet and Shiparo, 2008, Lithos) Jyotirmoy Paul | Indian Institute of Science | JUGS GEOGLE 14 01-08-2020

How do continents destroy? Hypothesis for craton survival: Cratons are lighter in density What about convective erosion? (Karato 2010) Jyotirmoy Paul | Indian Institute of Science | JUGS GEOGLE 15 01-08-2020

Convective erosion Do the cratons need to be strong? How strong? Jyotirmoy Paul | Indian Institute of Science | JUGS GEOGLE 16 01-08-2020

Cratons: Now and then Jyotirmoy Paul | Indian Institute of Science | JUGS GEOGLE 17 01-08-2020

Modeling evolution of cratons (Paul and Ghosh, 2020, EPSL) Jyotirmoy Paul | Indian Institute of Science | JUGS GEOGLE 18 01-08-2020

Digging deeper into the time Transition of tectonic regime ~ 3 Ga? Origin of plate- tectonics and stabilization of cratons are closely Stagnant-lid and Mobile-lid (Plate-tectonics) related? (Paul 2020, AGU Eos) Jyotirmoy Paul | Indian Institute of Science | JUGS GEOGLE 19 01-08-2020

Re-Search Interest Curiosity Imagination Jyotirmoy Paul | Indian Institute of Science | JUGS GEOGLE 20 01-08-2020

May not Join a PhD, if Of course you have a 01 Will prepare for jobs in these years! right enrol into a PhD program 02 anytime, No job in market, let’s do PhD but doing PhD is not an enrolment 03 Lots of money after PhD is over! Jyotirmoy Paul | Indian Institute of Science | JUGS GEOGLE 21 01-08-2020

Academic nomads India or Abroad? Jyotirmoy Paul | Indian Institute of Science | JUGS GEOGLE 24 01-08-2020

Disclaimer! All pros and myths can not be generalised. They do vary from cases to cases. Pros Indian PhD Family Can’t Travel/ enjoy life Indian PhD Root to Takes culture eternal Understanding Poor science the system Myths Jyotirmoy Paul | Indian Institute of Science | JUGS GEOGLE 25 01-08-2020

Disclaimer! All cons and myths can not be generalised. They do vary from cases to cases. PhD in abroad Cons Lot of Mental Money Health Abroad Supercool Racism advisors Adjusting to Indian system Quality PhD later Myths Jyotirmoy Paul | Indian Institute of Science | JUGS GEOGLE 26 01-08-2020

#GeoGRExit Promote anti-racism Sense of superiority still remains. When I told the same, people laughed, Now Americans are telling So, people are accepting. Jyotirmoy Paul | Indian Institute of Science | JUGS GEOGLE 29 01-08-2020
