We are living in an exciting time for technology, especially in the field of software. Computers now have the capability to simulate and analyze complex phenomena, including the intricate world of DNA. Each person has a unique DNA sequence that is about 3 billion letters long. This massive amount of data cannot be processed manually, so we rely on computer programs to help us understand how DNA is connected to various diseases.
My passion lies where biology meets computer science. There is an enormous database that contains information on all known organisms, from humans to monkeys, mice, viruses, and bacteria. Traditionally, when doctors suspect an infection, they consider factors like the patient’s age and symptoms—such as ear, heart, or brain issues—and make an educated guess about the infection type. They then order specific tests to confirm their hypothesis, like a strep test for suspected strep throat.
However, with new testing methods, we can screen for any infection with a single test, removing any bias. Instead of guessing, we analyze the sample to see what is actually present.
Consider the story of Joshua Osborn, a teenager from Cottage Grove, who faced a mysterious and severe illness. His case underscores the power of new DNA sequencing technologies in solving medical puzzles. Last spring, Joshua was just like any other teenager, eager to enjoy the outdoors. He said, “I feel wonderful today. It’s 80 degrees,” a stark contrast to the previous summer when he was in a coma.
Joshua’s health problems began with fevers and headaches, eventually leading to hospitalization. His father, Clark, remembers the ordeal of numerous tests, including scans and spinal taps, all failing to identify the cause. Despite extensive testing and significant costs, the medical team was stumped.
Eventually, they sought our help. We analyzed a small sample of Joshua’s cerebrospinal fluid, which surrounds the brain. Using advanced computer algorithms, we filtered out human DNA sequences and compared the remaining non-human sequences to a vast database of known organisms. We quickly identified a bacterium that Joshua likely contracted during a trip to Puerto Rico nine months earlier. Fortunately, this bacterium is treatable with penicillin. The doctor administered the medication that day, and Joshua felt better within 24 hours.
Joshua expressed his gratitude, saying, “I’m happy to be alive, and I have dreams that I’m looking forward to accomplishing.”
Data analysis is revolutionizing medicine, not only in diagnosing diseases but also in finding cures. Even after a cure is discovered, data is crucial in delivering treatments to patients. For instance, in the fight against polio in Africa, data ensures that vaccines reach everyone who needs them. The challenge is to make sure all children receive the vaccine three times.
To address this, we use satellite imagery and visual analysis to evaluate population coverage. We found that at the borders of different political areas, communities were often overlooked, with each group assuming the other was providing care. Additionally, we use GPS tracking on mobile devices to monitor vaccination teams’ movements. By analyzing this data, we can determine if we are reaching all children effectively.
Increasing vaccination coverage from 80% to 90% can be the difference between success and failure. The software that allows us to track team movements, analyze satellite images, and compile statistics is crucial in our mission to eradicate diseases. Systems thinking and the power of software are truly leading these advancements.

Engage in an activity where you analyze satellite imagery and GPS data to assess vaccination coverage in a simulated region. Learn how to identify gaps in coverage and propose solutions to ensure comprehensive vaccination efforts. This activity will enhance your understanding of data’s role in public health initiatives.
**Data and Medicine**
This is a remarkable era for software. We can now use computers to simulate a wide range of phenomena. Every individual has a DNA sequence that is approximately 3 billion letters long. This extensive sequence cannot be analyzed manually; it requires computer programming to navigate through the data and understand how DNA is linked to diseases.
My interests lie at the intersection of biology and computer science. There exists a vast database that encompasses all known organisms, including humans, monkeys, mice, viruses, and bacteria. Typically, when a doctor suspects an infection, they consider the patient’s age and symptoms—whether they are experiencing issues in the ear, heart, or brain—and make an educated guess about the type of infection. They then order specific tests based on that hypothesis. For instance, if strep throat is suspected, a strep test is conducted.
However, the testing we perform allows us to screen for any type of infection with a single test, eliminating bias in our approach. Instead of presuming it’s a specific infection, we simply analyze the sample to identify what is present.
A teenager from Cottage Grove has been taking life one day at a time after recovering from a serious, unidentified illness.

His health issues began last April with fevers and headaches, which progressively worsened, leading to hospitalization.
