Hyperight: Can you tell us more about yourself and your organization? What are your professional background and current working focus?
Hugo Fitipaldi: I am currently working as a postdoctoral fellow at the Department of Clinical Sciences at Lund University. My focus is on the application of data science frameworks to derive public health evidence from large health datasets.
Some might find my background somewhat unusual for someone currently working with data science and machine learning (ML). But I like to think my path echoes Steve Jobs’ notion of ‘connecting the dots’. He mentioned this idea in his memorable 2005 Stanford commencement address. ‘You can’t connect the dots looking forward; you can only connect them looking backward. So you have to trust that the dots will somehow connect in your future.’
I completed a BSc in Physiotherapy from Universidade Federal de Pernambuco (Brazil) in 2013, worked in clinical practice for a few years, and later completed a Masters in Public Health (MPH) from Lund University in 2018. It was during the MPH that I developed an interest in statistical modeling and shifted my focus to the analysis of epidemiologic data. This fascination led me to further my education with a PhD at the Lund University Diabetes Centre, where I delved into the application of data mining and AI-based frameworks to analyze health datasets, particularly focusing on epidemiology, public health, and systems medicine.
Currently, I am involved in projects where I use ML and deep learning (DL) to identify and validate prognostic and predictive biomarkers. These projects aim to address rapid aggressive disease progression in diabetic kidney disease (DKD) and identify potential drug targets. My research interests lie in the integration of health data from various sources such as OMICS, registers, and surveys. I aim to derive meaningful information that can potentially help future decision-making for healthcare.
I am grateful for the opportunities I have had during my path. This includes my involvement in the COVID Symptom Study (CSS) and contributing to the development of machine learning-based prediction tools for COVID-19 surveillance during the pandemic.
In summary, I am deeply passionate about the intersection of data science, artificial intelligence, and public health. I am dedicated to using my skills and expertise to contribute to meaningful research that can impact healthcare outcomes.

It will also discuss the potential for further refinement and development of these models using data mining and machine learning techniques.
Hyperight: Could you share some key challenges you faced in handling large-scale data from the COVID Symptom Study? How did data science and AI techniques play a role in overcoming these challenges?
Hugo Fitipaldi: Certainly. Dealing with large-scale data from the CSS posed unique challenges. Especially given that we were conducting this analysis in the midst of a global pandemic. At the time, our understanding of COVID-19 was still evolving. We were continually learning about the dynamics of the virus and its evolving symptomatology.
The CSS aimed to provide real-time insights into the spread of COVID-19. This required data to be processed and analyzed rapidly to identify trends and patterns as they emerged. It was a considerable challenge given the scale of the data involved. There were over 200 thousand participants in Sweden alone and over 4 million participants in total across the UK, US, and Sweden. Quality control was always a concern. Given that the CSS relied on self-reporting from participants, there was always the risk of inaccuracies or missing information in the data. Nevertheless, thanks to an unprecedented effort from various contributors, data continued to emerge from diverse sources. Coupled with our statistical methodologies, this helped validate and cross-check the CSS findings.
In overcoming these challenges, data science and AI techniques played a crucial role. ML algorithms and data mining techniques were instrumental in identifying key symptoms and interactions associated with COVID-19. By leveraging these tools, we were able to navigate through these challenges and gain valuable insights into the dynamics of COVID-19. This allowed us to make significant contributions to the understanding of the disease during the pandemic.
Hyperight: As a speaker on the Data Science & AI Strategy Stage, how do you see the intersection of data science and AI shaping the future of healthcare? Particularly, in the context of pandemics and emerging health challenges?
Hugo Fitipaldi: I see the intersection of these fields playing a crucial role in addressing current and future pandemics and health challenges. We are witnessing healthcare progress towards a data-centric and personalized approach, with AI and data science emerging asessential tools. The integration of these technologies enables healthcare professionals to analyze vast amounts of data and identify patterns, leading to earlier detection and prediction of disease outbreaks. Moreover, the personalization of healthcare with the help of AI and data science allows for tailored treatments and interventions, improving patient outcomes. As pandemics often disproportionately affect certain populations, such as the elderly or those with underlying health conditions, this personalized approach is particularly valuable.
The COVID-19 pandemic has demonstrated the urgent need for real-time data analysis and predictive modeling to inform public health decisions. Data science and AI have played a critical role in monitoring the spread of the virus, predicting hotspots, and guiding policy responses. Looking ahead, these tools will continue to be indispensable in detecting and responding to future pandemics and emerging health challenges.
