Subarna Bhattacharyya, PhD
Arctic Scientist and CEO, Climformatics
Subarna is a time series analyst interested in applying mathematical and statistical signal processing tools to analyze real-world engineering problems. She has been working towards understanding global climate change. In particular, she is applying mathematical and statistical tools to analyze and therefore understand past climate change, and be able to predict probable future climate change and its impact from a risk assessment perspective. Modeling and simulation of possible scenarios of Abrupt Climate Change using earth system models like CESM, greenhouse emissions, analyzing El Nino and tropical storms in a warming scenario, understanding precipitation changes in a climate change scenario and its possible impact on water supply, impacts of solar variability on various tropospheric processes and their mechanisms are some of her current research interests. She is interested in climate risk modeling and assessment as well. Her academic journey began with studying physics, civil (stochastic structural dynamics) engineering and proceeded to climate data analysis, climate modeling and simulation, entraining in its wake widely-interdisciplinary analytical skills (statistical signal processing, wavelet analysis and non-linear dynamics) which aid her research.

Detelina Ivanova, PhD
Arctic Scientist and Lead Climate Modeler, Climformatics
Detelina P. Ivanova is a climate modeling scientist for both Climformatics and at Scripps Institution of Oceanography. Detelina does research in Oceanography and Climate. Her current projects are in ultra-high resolution global ocean-ice and climate modeling. Her 30 publications can be found at: https://www.researchgate.net/profile/Detelina_Ivanova

Velimir Mlaker
Lead Computer Scientist, Climformatics
Velimir Mlaker is the lead Computer Scientist for Climformatics. His background spans Climate Model diagnosis, climate data analysis tools, computer vision, machine learning, parallel signal processing, string processing, and general development in Python and C++.

Armond Cohen
Executive Director, Clean Air Task Force
Armond Cohen is co-founder and Executive Director of the Clean Air Task Force, which he has led since its formation in 1996. In addition to leading CATF, Armond is directly involved in CATF research and thought leadership on the need for a broad range low carbon technology options. Prior to his work with CATF, Armond founded and led the Conservation Law Foundation’s Energy Project starting in 1983, focusing on energy efficiency, utility resource planning, and electric industry structure. He is Chair of the Electric Power Research Institute’s Advisory Council, a member of the Keystone Energy Board, a founding board member of the Center for Responsible Shale Development, and co-Chair of the Nuclear Innovation Alliance. Armond is an honors graduate of Brown University and Harvard Law School.

Carol Sontag
Clinician, Palo Alto Unified School District
Carol is an RN, BSN who who has worked as a nurse, clinical research coordinator and clinical research consultant at SCVMC, UCSF and Stanford University Hospitals. She has worked as a diabetes nurse clinician at Palo Alto Unified School District since 2007. Carol has been interested in conservation and climate change sincce the late 1980s and has been a supporter of many local and national environmental groups. Her primary focus is the effect of climate change on children as seen in endocrine, respiratory and overall children’s health. Carol is worried that the brunt of climate consequences will fall on those who do not have a voice in current global policies. She is excited to be a part of an organization that is solution oriented and offers hope for future generations.
