The Polymer Materials Design Lab studies polymer materials that incorporate mechanisms by which molecules bind to each other reversibly. Using host-guest interactions between cyclodextrin, a host molecule, and guest molecules as crosslinks, the lab works on making materials whose scratches disappear and materials that are tough. Research themes include self-healing materials, as well as tough materials, adhesive systems, actuators, composite materials, and repolymerization and degradation using enzymatic reactions. The name "Takashima Lab" is also used in the contact information on the lab's website.

The Polymer Structural Science Lab studies how biological molecular machines work, such as the flagellar motors that bacteria use to swim. Bacteria such as E. coli and Salmonella swim by rotating tiny motors made of proteins. The lab investigates how molecular machines like this motor operate through atomic-level three-dimensional structure analysis and reconstitution of the molecular machines. The lab's website introduces it under the name "Imada Lab."

The Supramolecular Functional Chemistry Lab aims to create functional materials that combine the strengths of biopolymers (especially monoclonal antibodies) with those of synthetic polymers and low-molecular-weight compounds by forming composites of them. The lab extracts the essential structural features of biomolecules, designs and synthesizes molecules and polymers that take over those roles, and aims to achieve new functions in materials that assemble in a specific manner. In recent years, the lab has also been working on sulfur-containing polymers made from sulfur, a surplus resource.

The Polymer Solution Lab studies the conformations that polymers adopt in solution, the aggregates formed by self-assembly, and phase separation of solutions. Polymers in solution can adopt diverse conformations, and because of this conformational freedom they show distinctive properties not seen in low-molecular-weight compounds. The lab investigates their behavior from a physical chemistry perspective. Using scattering methods such as small-angle X-ray scattering and light scattering together with spectroscopy, the lab aims to quantitatively clarify structures and physical properties, from isolated polymer chains to aggregates and nanocomposites.

The Environmental Safety Chemistry Lab is part of the Safety and Health Management Division at Osaka University and conducts research on safety and on the environment. The lab analyzes trends in accidents occurring on campus and develops safety education methods based on the results. It is also pursuing research on polymer electrolytes aimed at inherently safe lithium-ion secondary batteries, among other topics.

The Plant Cell Fate Regulation Lab studies how plant cells determine their own fate, using vascular tissue, which transports water, sugars, and other substances, as its subject. When leaves are soaked in a culture medium containing hormones, vascular cells can be produced with high efficiency within a few days. The lab developed this differentiation induction system, called VISUAL, itself and uses it in its research. The lab is also developing imaging that uses the mechanisms of bioluminescent organisms such as fireflies to capture changes in cell fate over time. The plants used as materials include Arabidopsis, tomato, tobacco, ginkgo, the moss Physcomitrium patens, and the liverwort Marchantia polymorpha.

The Plant Physiology Lab carries out a wide range of research on plants, algae, and other organisms, centered on photosynthesis. The backbone-like machinery that supports photosynthesis is similar across many organisms, but the reactions surrounding it strongly reflect the characteristics of each organism. By studying these reactions surrounding photosynthesis, the lab seeks to understand the ways of life of plants, algae, bacteria, and other organisms. Current research themes include the photosynthetic quotient, leaf senescence, the internal structure of chloroplasts, and the symbiosis between corals and zooxanthellae.

The Animal Morphology Lab conducts natural history research on dicyemids, mesozoans that live in the renal sacs of cephalopods. Building on taxonomy, the lab investigates them from many perspectives, including morphology, development, phylogeny, ecology, evolution, and genomics. Viewing the renal sac as a small natural laboratory, the lab explores how dicyemids live in this environment and what interactions occur among coexisting species. The lab also conducts natural history research on animal groups other than dicyemids, aiming to understand the nature of living organisms.

The Organ Morphogenesis Regulation Lab uses Xenopus embryos and tadpoles to study how the shapes of tissues and organs are formed. The body is made of tissues and organs that embody the beauty of form designed to maximize function (functional beauty). These shapes are assembled during development through the precise movements of individual cells, but much of the mechanism, including what gives the cells their instructions, remains a mystery. The lab aims to uncover the mechanisms by which cells form and control shape while coping with stress from the environment. On the lab's website, it is presented under the name "Shindo Lab."

The Comparative Neurobiology Lab studies how invertebrates such as insects and mollusks process information about time in their brains and nervous systems. Using the innate circadian clock, the lab investigates photoperiodism, the mechanism by which organisms read the season from photoperiod information, as well as the mechanisms behind the unique behaviors timed by the circadian clock. Research subjects include the bean bug (Riptortus pedestris), the large black chafer (Holotrichia parallela), which has a circabidian rhythm with a 48-hour period, and the great pond snail (Lymnaea stagnalis), a freshwater snail. On the lab's website, it is presented under the name "Shiga Lab."
