            <p>Hello and welcome! I am Abel Souza, an Assistant Professor in the <a href="https://engineering.ucsc.edu/departments/computer-science-and-engineering/" rel="external nofollow noopener" target="_blank">Computer Science and Engineering</a> (CSE) Department at <a href="https://ucsc.edu" rel="external nofollow noopener" target="_blank">UC Santa Cruz</a>.</p>

<p>My research centers on expanding the understanding of computing systems, from small embedded devices to large scale data centers, encompassing resource planning and the deployment of optimal strategies for distributed  and data-intensive systems that support AI, Machine Learning, and web workloads.
Recently, my work has expanded into sustainable, carbon-aware approaches to designing and managing cloud data centers and cyber physical systems, with the goal of achieving zero-carbon operations.</p>

<p>A key theme in my research explores the efficient application of predictive analytics methods to process and model vast amounts of data, tailoring resource management holistically to applications. 
This involves determining the optimal quantity and type of resources to allocate, as well as the most effective deployment times and locations.</p>

<p>Prior to joining UCSC, I was a Postdoctoral Researcher at the <a href="https://www.umass.edu" rel="external nofollow noopener" target="_blank">University of Massachusetts Amherst</a>, and a PhD student in the <a href="https://www.cs.umu.se/en" rel="external nofollow noopener" target="_blank">Department of Computing Science</a> at <a href="https://www.umu.se/en" rel="external nofollow noopener" target="_blank">Umeå University</a> (Sweden). At UMass, I worked with Prof. <a href="https://people.cs.umass.edu/~shenoy/" rel="external nofollow noopener" target="_blank">Prashant Shenoy</a> in the <a href="http://lass.cs.umass.edu" rel="external nofollow noopener" target="_blank">Laboratory for Advanced System Software</a>. At UmU, I worked in the <a href="http://http://cloudresearch.org/" rel="external nofollow noopener" target="_blank">Autonomous Distributed Systems Lab.</a> under the guidance of Dr. <a href="https://scholar.google.com/citations?user=TMoM51MAAAAJ&amp;hl=en" rel="external nofollow noopener" target="_blank">Johan Tordsson</a> and Prof. <a href="https://people.cs.umu.se/elmroth/" rel="external nofollow noopener" target="_blank">Erik Elmroth</a>.</p>

<p><strong>I am seeking PhD, master’s, and undergraduate students to supervise and collaborate with. If you’re interested in working in Cloud, Distributed, and/or Sustainable computing, please feel free to reach out via <a href="mailto:[email protected]">email</a>.</strong></p>

            <p>Cloud platforms have been focusing on reducing their carbon emissions by shifting workloads across time and locations to when and where low-carbon energy is available. Despite the prominence of this idea, prior work has only quantified the potential of spatiotemporal workload shifting in narrow settings, i.e., for specific workloads in select regions. In particular, there has been limited work on quantifying an upper bound on the ideal and practical benefits of carbon-aware spatiotemporal workload shifting for a wide range of cloud workloads. To address the problem, we conduct a detailed data-driven analysis to understand the benefits and limitations of carbon-aware spatiotemporal scheduling for cloud workloads. We utilize carbon intensity data from 123 regions, encompassing most major cloud sites, to analyze two broad classes of workloads – batch and interactive – and their various characteristics, e.g., job duration, deadlines, and SLOs. Our findings show that while spatiotemporal workload shifting can reduce workloads’ carbon emissions, the practical upper bounds of these carbon reductions are currently limited and far from ideal. We also show that simple scheduling policies often yield most of these reductions, with more sophisticated techniques yielding little additional benefit. Notably, we also find that the benefit of carbon-aware workload scheduling relative to carbon-agnostic scheduling will decrease as the energy supply becomes “greener”.</p>
