The Academy of Athens (Greek: Ακαδημία Αθηνών, Akadimía Athinón) is Greece’s national academy, and the highest research establishment in the country. It was established in 1926, and operates under the supervision of the Ministry of Education. The Academy’s main building is one of the major landmarks of Athens.

Dr Katsanikas duties in his new role will be the research and the supervision of research programs, postdoctoral researchers and Master and PhD theses and the teaching at postgraduate programs. He expects to take up this position in early 2021.

Dr Katsanikas joined the Champs project in 2017, one of our first PDRA cohort, based in Bristol under Professor Wiggins supervision. He has made great progress during his time working on the project, so this next step in his career is well deserved and recognition of what an excellent researcher he is.

We wish Dr Katsanikas all the best for the future.

Event report: Symposium – ‘Crowd-sourcing Machine Learning in NMR’ Thursday 5th Mar 2020.

The rise of machine learning (ML) has led to an explosion in potential strategies which may be used to learn from data in order to make scientific predictions. For physical scientists who wish to apply ML strategies to a particular domain, the vast number of strategies available has made it difficult to make an a priori assessment of what strategy to adopt. This is further complicated when similar domains have not been previously explored in the literature.

Recently, CHAMPS PDRA Dr. Lars Andersen Bratholm and collaborators worked with Kaggle to design a competition which encouraged data scientists around the world to develop ML models for predicting pairwise nuclear magnetic resonance (NMR) properties for synthetically relevant chemical compounds.
The success this strategy has cultivated highlights the potential of crowd-sourced ML approaches across a range of scientific domains and the CHAMPS symposium “Crowd-sourcing machine learning in NMR” took place on the 5th of March to communicate this message to researchers in the Bristol area.

The symposium started off with Professor Craig butts and PhD student Will Gerrard from the University of Bristol presenting how modelling of NMR properties with DFT and ML can accelerate the drug design process. This was followed by Addison Howard from Kaggle introducing the Kaggle platform, background to the company and interesting findings from the CHAMPS competition. The early non-technical session ended with Lars Bratholm conveying the main findings of the competition from the organizers point of view, namely what can be gained from combining all the different approaches, and how the collaborative environment of Kaggle is something that we can learn from in academia.

The afternoon session turned more technical and featured representatives from six of the top performing teams who all presented their approaches to the competition. The talks of Brandon Anderson, Luka Stojanovic, Milos Popovic, Sunghwan Choi, Andres Torrubia and Devin Wilmott all spurred great discussion with audience, which continued the following day with the competition organizers.

Symposium – Title: ‘Crowd-sourcing Machine Learning in NMR’, Thursday 5th March 2020

Symposium – Title: Crowd-sourcing Machine Learning in NMR

Following on from the success of the Kaggle competition that Champs PDRA Lars Anderson Bratholm ran last year he is now organising a Symposium to be held on Thursday 5th March 2020.

Title, abstract and schedule below (subject to change):

Crowd-sourcing Machine Learning in NMR

Abstract:
The rise of machine learning (ML) has led to an explosion in potential strategies which may be used to learn from data in order to make scientific predictions. For physical scientists who wish to apply ML strategies to a particular domain, the vast number of strategies available has made it difficult to make an a priori assessment of what strategy to adopt. This is further complicated when similar domains have not been previously explored in the literature.
Recently, we worked with Kaggle to design a competition which encouraged data scientists around the world to develop ML models for predicting pairwise nuclear magnetic resonance (NMR) properties for synthetically relevant chemical compounds. Over 3 months, we received 47,800 ML model submissions from 2700 teams in 84 countries, with the top models outperforming our own previously published methods. The success this strategy has cultivated highlights the potential of crowd-sourced ML approaches across a range of scientific domains.

This symposium will introduce the background and main findings of the competition, including the context of computational NMR, the Kaggle platform and presentations from the top performing teams of the competition.

CHAMPS Book Sprint – December 6-9, 2019

CHAMPS Book Sprint

On December 6-9, 2019, CHAMPS PDRAs Makrina Agaoglou, Broncio Aguilar Sanjuan, Rafael Garcia-Meseguer, Francisco Gonzalez-Montoya, Matthaios Katsanikas, Vladimir Krajnak, Shibabrat Naik, PI Stephen Wiggins, and collaborator Victor Jose Garcia-Garrido of the Universidad de Alcala in Spain held a book sprint.

A book sprint is a method of creating a book collaboratively in a short period of time. The book sprint was held at Engineers House in Bristol which afforded an atmosphere promoting intensive collaboration with minimal distractions. The book is an account of our results, approach, and future directions on the phase space approach to chemical reaction dynamics. The book was produced using Jupyter Book and is available at www.chemicalreactions.io. The result is the book entitled “Chemical Reactions: A Journey into Phase Space”. It is our intention that the book will appeal both to mathematicians and to chemists and will serve as an entry into the field. Indeed, the GitHub framework provides a mechanism for scientific collaboration and we invite the interested scientific community to contribute to the further development of the book. Instructions for this are on the GitHub site for the book (https://github.com/champsproject/chem_react_dyn).

Joint CHAMPS and Leeds Physical Chemistry seminar “Quantum Trajectories in Phase Space” Wednesday 18th September 2019

On Wednesday the 18th of September a joint CHAMPS and Leeds Physical Chemistry seminar “Quantum Trajectories in Phase Space” took place in Leeds . The talk was given by Prof Craig Martens from University of California, Irvine. Although it is a physical/computational chemistry seminar it was of general interest, as it was focused on unusual formulation of quantum mechanics. We almost always think about quantum mechanics in terms of wave function and waves of probability, but there are other ways of looking at it. But Prof Martens presented one an approach, in which quantum mechanics is formulated very similar to classical mechanics, with the difference that neighbouring classical trajectories are not independent. They are entangled and push each other in a very specific way, as if there were many parallel worlds interacting with each other. The talk was attended not only by physicist, mathematicians and computational chemists, but also by a number of experimental organic and inorganic chemists.

Although it is a physical/computational chemistry seminar it can be of general interest, as it will be about an unusual formulation of quantum mechanics. We almost always think about quantum mechanics in terms of wave function and waves of probability, but there are other ways of looking at it. Craig Martens will present one of those approaches, in which quantum mechanics is just like classical, with the difference that neighbouring classical trajectories are not independent. They are entangled and push each other in a very specific way, a bit like there were many parallel worlds interacting with each other.

CHAMPS Visitor: Professor Joel Bowman, the Samuel Candler Dobbs Professor of Theoretical Chemistry at Emory University in Atlanta.

The CHAMPS Project was pleased to host Professor Joel Bowman, the Samuel Candler Dobbs Professor of Theoretical Chemistry at Emory University in Atlanta, Georgia, for a visit during September 3-5, 2019. Professor Bowman presented a seminar entitled “A Machine Learning Approach for Prediction of Rate Constants”, which described a new application of machine learning in chemistry. Actually, the talk had two independent halves, with the first half of the talk devoted to a discussion of the current “state-of-the art” of the roaming mechanism for chemical reactions, which included some discussion of the manifestation of quantum effects in roaming .The CHAMPS PDRAs (as well as the PI) particularly enjoyed a two hour, informal, round table discussion, covering many aspects of contemporary reaction dynamics, as well as a bit of much appreciated career advice.

Molecular Dynamics Outreach @ the Wickham Theatre!

Figuring premier @ the Wickham Theatre!
Posted on September 30, 2018 by David R Glowacki

The last couple weeks have seen some interesting outreach developments! With support from Arts Council England, the EPSRC-funded CHAMPS programme, the Leverhulme Trust, and the Royal Society, David Glowacki and team worked on a project called “Figuring” at the Wickham theatre in the University of Bristol’s Department of Drama, with a talented team drawn across artistic, scientific, and technological practices. On 21 Sept, they worked to premier Figuring to an audience of artists, producers, and technologists. This follows on from a previous prototype showing of Figuring at the Knowle West Media Centre, as part of their Commons Sense programme.
The aim of Figuring is to investigate what can be created when moving, sensing bodies are embedded in simulated virtual worlds, and what arises when somatic and movement based practices are combined with Narupa, a state-of-the-art multi-person VR framework for molecular dynamics simulation, which has been developed within the Intangible Realities Laboratory over the last several years.
Figuring takes its name from its intention to explore ‘string figures’, in both the real world and also in the virtual world. String figures are created through simple movements of folding, looping, twisting, and knotting strings between the hands, fingers and thumbs of one or more people.

Figuring team members experimenting with the dynamics of physical strings

During our time at the Wickham theatre, members of the CHAMPS project worked with a group of dancers to facilitate experiments with both physical and virtual strings. For the ‘raw material’ of the virtual strings, the team relied on real-time molecular dynamics simulations of proteins: the molecular strings from which life is woven. Narupa enables audiences to reach out and touch simulated proteins: folding, looping, twisting, and knotting them.
Despite their virtuality, Figuring audiences reported ‘felt’ sensations whilst manipulating virtual simulations of molecular strings. Moving forward, we hope to better understand the origins of such sensations, how they map onto their physical and tangible analogues, and how different sensory and somatic practices might enable us to understand perception across real, virtual and imagined environments.

Figuring represents a collaboration between a diverse team with broad interests, led by David Glowacki and somatic/movement artist Lisa May Thomas. Alex Jones, Dr. Tom Mitchell, and Prof. Joseph Hyde helped to devise algorithms for generating sound from the virtual string dynamics. Computer Scientist Mike O’Connor and Mark Wannacott played a key role in developing the VR interaction capabilities and aesthetic, and Helen Deeks provided key advice on human-computer interaction strategies. Somatic and movement practitioners included Laila Diallo, Ben McEwan, Bryn Thomas, Ania Varez, Will Dickie, Fernanda Munoz-Newsome and Anne-Gaëlle Thiriot. Production is by Emma Hughes, dramaturgy by Tanuja Amarasuriya, and set design by Phillipa Thomas. Photos are by Paul Blakemore and Silvia Cardarelli-Gronau, and film by Adam Laity.
