In 1999, he became Lecturer (Full Professor from 2007) and Head of the Solar Physics team in the Physics Department of the University of Warwick, UK. His main area of research is related to the observational study and theoretical modelling of magnetohydrodynamic waves in plasma structures on the Sun's Corona, new methods of plasma diagnostics, radiophysics of the Sun, and quasi-periodic processes in solar and stellar flares. From 2011-2014, he served as President of the European Solar Physics Division of the European Physical Society. In 2015, he was honored by the Payne-Gaposchkin Medal and Prize of the Institute of Physics, UK.

Prof. Dipankar Banerjee is currently the director of the Aryabhatta Research Institute of Observational Sciences (ARIES), Nainital. He is an astrophysicist with a bachelor’s degree in physics (St. Xavier’s college) and master’s degree in theoretical physics from University of Kolkata, India. He has obtained his PhD from Indian Institute of Astrophysics and completed two postdoctoral tenures in reputed institutions in Europe. He is the co-chair of the Science working group of the “Aditya” mission. Aditya is the first dedicated Indian mission to study the Sun, expected to be launched by ISRO around 2022. He is also the project coordinator for the National Large-Solar Telescope Project (NLST). NLST is a proposed 2-meter ground-based telescope planned to be installed at a Himalayan site. He is also involved with NASA’s PUNCH mission. Dr. Banerjee has more than 120 peer-reviewed publications witharound 3000 Citations in international journals. He is currently supervising 6 PhD students while 11 of his students have completed their PhDs.

Dr. Bo Li received his BSc in Nuclear Physics and Technology from the University of Science and Technology of China (USTC) in 1996. He went on to pursue his post-graduate study in Space Physics at the same institution and received his PhD in Geophysics in 2001; the thesis being on magnetohydrodynamic waves in the highly inhomogeneous chromosphere and corona of the Sun. From 2002 to early 2009 he was a research assistant in Aberystwyth University, UK. Since 2009, he has been a professor at the School of Space Science and Physics of Shandong University in Weihai, China. Bo Li’s current research interests are primarily with low-frequency waves and oscillations in the solar atmosphere and in a broad context, solar atmospheric seismology. He has extensive experience in multi-fluid modeling of the solar wind as well; paying special attention tothe role of hydromagnetic waves/turbulence in wind heating and acceleration.

Dr. Tongjiang Wang received his BSc and MSc in Astronomy and Astrophysics from Nanjing University, China in 1991 and 1994, respectively. He received his PhD degree in Solar Astrophysics from National Astronomical Observatories of China, Chinese Academy of Sciences in 1998. His PhD research was on observational studies of the magnetic field in solar active regions (Supervisor Prof. Guoxiang Ai) including various topics such as calibrations of the Multi-Channel Solar Telescope, the relationship of evolution of ARs’ vector magnetic field, electric current, and magnetic topology with solar flare eruptions, as well as the hemispheric distribution of ARs’ current helicity. After his PhD, he went on to pursue his postdoctoral studies at various institutions: From 2000-2001 PostDoc at Kwasan & Hida Observatories, Kyoto University, from 2001-2005 PostDoc at Max-Planck-Institute for Solar System Research, and from 2006-2007 research scientist at Montana State University. Since 2007 he has been a research associate at the Catholic University of America and NASA Goddard Space Flight Center. Dr. Wang has a wide research interest in solar coronal physics including the dynamics, oscillations and flare activity in solar active region coronae using EUV spectroscopic and imaging observations from various space missions and MHD modelling. He also works on reconstructions of 3D electron density of the corona using the tomographic techniques from the white-light coronagraph images to understand the coronal variability.

Dr. Ivan V. Zimovets received his BSc and MSc in Applied Mathematics and Physics from the Moscow Institute of Physics and Technology (MIPT, State University) in 2005 and 2007, respectively. The topics of his bachelor's and master's theses were the transport of solar cosmic rays in the three-dimensional corona and heliosphere under the supervision of Dr. A.B. Struminsky at the Department of Space Plasma Physics at the Space Research Institute of the Russian Academy of Sciences (RAS). While there in 2010, he defended his PhD thesis on “Quasi-periodic pulsations of X-ray emission in solar flares." He has worked at the Space Research Institute as a junior researcher from 2010-2012, as a researcher from 2012-2016, and as a senior researcher from 2016 to the present. In 2016-2018, he held parallel positions as a visiting scientist at the International Space Science Institute – Beijing (ISSI-BJ) and Postdoc at the National Space Science Center (NSSC) of the Chinese Academy of Sciences (CAS). He visited the High-Energy Solar Physics group led by Prof. W.-Q. Gan at the Purple Mountain Observatory of CAS under the support of the CAS President’s International Fellowship Initiative (PIFI) for Visiting Scientist in 2018-2019. Scientific interests of I.V. Zimovets include observational studies of solar flares, in particular, quasi-periodic pulsations in various spectral ranges, coronal mass ejections, MHD waves in coronal plasma, solar cosmic rays, design and development of X-ray telescopes, and charged particle detectors. He has been Deputy Scientific Director of the “Interhelioprobe” space mission and Scientific Secretary of the Physics of the Sun section of the Space Council of RAS since 2013.

Dr. Maurizio Falanga received his university degree for Theoretical Physics and Astronomy at the University of Basel, Switzerland in 1998 (Univ. degree thesis Advisor: Prof. F.-K. Thielemann). In 2002, he received his PhD degree in astrophysics from the University of Rome “La Sapienza”. For the PhD entrance examination, he was ranked 4/80. His PhD thesis work included theoretical General Relativistic ray-tracing calculations to reproduce the light curve emitted by matter orbiting in the strong-field regime around a black hole or from a neutron star surface (Advisor Prof. L.
