In March 2016, I co-chaired the Protoplanetary Discussions conference, held in Edinburgh, UK. The rationale of the conference was to invite observers from all wavelength regimes to share their latest results with modellers from the thermo-chemical and hydrodynamic communities in order to foster collaboration across these often separate fields. In addition to the standard format of invited and contributed talks, we also arranged specialised discussion sessions, allowing participants to interact in closer and more collaborative ways.

As a result of two of these discussion sessions, we wrote a overview paper concerning the forthcoming grand challenges of protoplanetary disc modelling - the inclusion of dust and gas hydrodynamics, magnetic fields, radiation transfer and chemical evolution in a self-consistent way. Rather than being a tradiational review, we preview the challenges faced with incorporating these often distinct, but fundamentally interconnected topics. You can view the paper here.
