Since March 2020, we have refocused efforts towards helping combat +the COVID-19 pandemic, by supporting informed decision-making at federal, state, +and local levels of government and in the healthcare sector. Until now, we've +been pretty "heads down" with our work, and slow to communicate what we've been +up to. But at last ... Delphi finally has a blog! This first post serves as an +introduction of sorts. Future posts will dive deeper into our various projects. + +## A Little Bit About Us + +We (Roni and Ryan) are co-leads and co-founders of the Delphi group. +When we started the group back in 2012, +our mission was to develop the theory +and practice of epidemiological forecasting, with a long-term +vision of seeing this technology become as universally accepted +and useful as weather forecasting is today. +In the following years, we developed both nowcasting and forecasting models, +focusing primarily on seasonal influenza in the US. +Our forecasting system is a perennial top finisher +in the Centers for Disease Control's annual forecasting challenges. +In 2019, we were named one of the CDC's two +Centers of Excellence for Influenza Forecasting. + +Back when we formed the group in 2012, +the "original four" members were David Farrow, Logan Brooks, Roni, and Ryan. +By early 2020, pre-pandemic, we'd grown to about 7-8 members in size, +and were happily and steadily making progress on flu forecasting and nowcasting, +and making headway into dengue and norovirus. +To learn about the work our group has done in the past, +including some papers we've written, software tools we've built, +and the real-time epidemiological data server we've been deploying since 2016, +check out `r blogdown::shortcode_html("reflink", "/", "our website")`. + +When the COVID-19 pandemic arrived, we focused all our attention on it. +Our Delphi team +quickly grew to 30+ members, and is still growing. +Most of our members are volunteers, +drawing talent from within CMU and several other universities, +including Stanford, UC Davis, and USC, and also from industry. +The pace has been intense and dizzying at times, +and we're infinitely grateful for the contributions +and commitment of all our new members---we'd be nowhere without them. +See `r blogdown::shortcode_html("reflink", "team", "here")` +for a list of the Delphi team members. + +With new members comes a new breadth of expertise: +our expertise now covers statistical modeling, computation, +systems engineering, user interfaces, visualization, +digital epidemiology, and epidemic forecasting. +We've been extremely fortunate to have developed +several new relationships with stakeholders and supporters in government, +the healthcare sector, and the tech industry; and of course, +we're proud and grateful for our existing relationships, +especially our longstanding relationship with the CDC. + +## Our Mission and Strategy + +While Delphi's long-term mission remains to advance the theory and practice of +epidemic forecasting, since March 2020 our goals are to help combat the COVID-19 +pandemic and save lives and livelihoods. +We aim to support informed decision-making at federal, +state, and local levels of government and in the healthcare sector. +Whenever possible, we strive to make our work useful +to the private and public sectors, other researchers, +the press, and the general public. + +Our strategy: + +1. Improve pandemic situational awareness and understanding + by providing comprehensive, geographically-detailed, + and continuously-updated indicators of pandemic activity and its impact, + helping to make meaning out of the pandemic information deluge. + +2. Support local, state, and federal governments' + ongoing decision-making in their attempts to balance + public health concerns with economic preservation, + by providing validated, verifiable, localized, + short-term forecasts of epidemic spread and healthcare demand, + under any assumed level of the local population's mobility and distancing + behavior. + +3. Analyze and demonstrate the impacts of governments' + past tightening or loosening of mitigation measures + (e.g., opening or closing schools or businesses, + imposing or lifting bans on gatherings, shelter in place orders, etc.) + on a population's mobility and distancing behavior. + +4. Engage continuously with our target users to communicate + our findings, and inform our directions and priorities. + +5. Make our products useful and accessible to other + researchers and tool developers, to amplify their impact. + To that end, we'll continue to make everything we invent or produce + publicly and freely available as soon as possible + and to the greatest degree allowed, including models, + algorithms, software, tools, estimates, and forecasts. + +## What We've Been Up To + +So what have we been doing since March? +We've been working towards our strategic goals above, +and have made good progress on some of them. + +Here's a quick summary: + +- We've built a number of new indicators of COVID-19 activity. + These are fine-grained geographically + (most of them are available at the US county level) + and temporally (all of them updated daily). + They are designed to shed light on the current picture of COVID in the US, + beyond the typical publicly-available metrics like confirmed cases and deaths. + +- Some of our indicators are based on massive-scale surveys that we’re running + through partnerships with Facebook and Google, and others are based on + aggregated counts from massive medical claims data sets through partners like + Change Healthcare. + +- We've built a `r blogdown::shortcode_html("apireflink", "api/covidcast.html", "public API")`, + and `r blogdown::shortcode_html("apireflink", "api/covidcast_clients.html", "R and Python packages")`, + to serve our indicators to researchers and the public. This API provides new + data daily. + +- We've built `r blogdown::shortcode_html("reflink", "covidcast", "interactive maps and graphics")` to + display our indicators, and better inform the public and decision-makers. + +- We've developed forecasts of the future spread of the pandemic, + validated them prospectively, and started submitting them to CDC. + +In subsequent posts, we'll dive deeper into many of these projects, and touch on +what's next for us (a lot... in many ways, we feel that our most important work +is still ahead of us). Until next time!
