Q1 Illinois currently has 138 data centers, with 8 underway, and plans for 29 more. Additionally, the cost of electricity and water are on the rise with nearby data centers straining current resources in combination with increased energy costs to consumers. Data centers also have several environmental and health impacts, such as significant water usage and noise pollution, which can lead to decrease in net economic gains. What policies, if any, do you support in managing existing data centers or establishing additional data centers? What specific plans do you have, if any, to mitigate utility cost burden for residents? Why these steps?

Energy

Data centers across Illinois have gone up very quickly in recent years, often with no or very little public input. I have heard claims that “closed loop” data centers are much less impactful on water usage and contamination, but I have yet to see the studies confirming that. As it stands today, we have surging energy costs, critical water shortages affecting quality and aquifer stability, and continuing to build data centers that worsen these issues is irresponsible. I support policies that will require existing data centers to mitigate negative community impact such as noise, water, and light pollution, as well as energy and water usage. I support legislation that would require community input before new data centers are constructed, as well as requiring data centers to include with development green energy solutions (ie solar). I support legislation requiring third-party studies to determine impact of data centers on our communities on an ongoing basis.

Q2 Research activities in Illinois heavily depend on federal funding. However, federal funding cuts for science research and agencies like the NIH and National Science Foundation leaves the future for science research less assured. What policies, if any, do you support or plan to implement to secure funding for continued science research at either the state or federal level?

Science Funding

I support funding for scientific research, and have been extremely disappointed to see cuts at the federal level. While I do not have specific policy plans to secure funding at the state or federal level, I would support others’ plans to provide funding.

Q3 Illinois is an agricultural hub, making it an important factor for the state’s economy. What policies or plans do you have, or support, to support Illinois agriculture against changing weather patterns?

Climate

The impact of the changing weather patterns on our agriculture is complicated, and it needs coordination among many different sectors to address it. First, we need to do everything we can to mitigate the human impact to changing weather patterns. Second, we need to identify crops, both specific types and broad types, that are resistant to big changes in water, temperature, and fertilizer changes. The most difficult aspect of the changing weather patterns is the unpredictability of it; some weeks are incredibly wet with severe storms, only to be followed by weeks of drought. This seriously complicates identifying crops that can withstand a growing season, as the weather becomes more unpredictable. The third step that I want to see taken is improvements on how we fertilize and irrigate our crops. Advancements have been made over the years to improve water conservation for crops, but as we confront statewide issues of depleted aquifers, we need to continue research into water conservation. Likewise regarding fertilizer, the use of fertilizer greatly improves the yield and quality of crops, but at an incredibly high costs, especially this year. Sustainable farming research should also be continued to improve farming practices that limit the need for fertilization.

Q4 Scientific issues increasingly influence public policy. When developing policy positions or making decisions on topics involving science, how do you seek out information, evaluate scientific evidence and expert input, and ensure your decisions are well informed? If you can, please share an example of when this process influenced your perspective or decision.

Trust in Science

When seeking out information on any topic, I look for sources from subject matter experts that cite peer-reviewed articles. I look for studies that question and build off each other, and I look to experts to analyze the quality of the date that is collected.

When considering the efficacy and safety of vaccines, I look to studies by medical doctors, and the testimony of medical doctors in further analyzing those studies. My own experiences have been that the flu vaccine did not prevent my children from contracting the flu, though as a new parent I expected them to be fully protected. I learned from their pediatrician that, while it doesn’t fully protect someone from contracting the flu, it does make it less likely, and it very likely helped my children’s immune systems to fight it off quickly and with minimal complications. Studies that I have read, and medical professionals who have analyzed those studies have supported those claims.

Q5 Measles and whooping cough (pertussis) cases are on the rise in Illinois, with multiple outbreaks in 2026. How have you, how do you plan to, address this public health concern? How will you plan to work with relevant stakeholders (epidemiologists, scientists, physicians, for example) to mitigate this problem?

Public Health

I support closing loopholes that allow people to forego vaccines, such as religious exemptions. Vaccines are a public health concern, and I believe that anyone who comes into contact with others through work or school should be required to receive vaccines determined to be critical by a team of medical experts.
